Summarize the following court judgment. Civil Appeal No. 1815 of 1969. Appeal by Special Leave from the Judgment and Decree dated the 3rd October	 1964 of the High Court of Judicature at Patna in Appeal from Original Decree No. 152 of 1959. P.K. Chatterjee and Rathin Das for the Appellant. S.V. Gupte and B.P. Singh for Respondents 1 2. 1003 Santok Singh for Respondents 3 4. The Judgment of the Court was delivered by CHANDRACHUD	 J. One Trilok Prasad Singh	 who was the last male holder in his line	 died on May 12	 1948 leaving behind his widow Kachnar Kuer and his step mother Sheo Kuer. On February 12	 1956 Kachnar Kuer executed two registered deeds. By one of these she adopted a son to her deceased husband and by the other	 which is described as a Deed of Arpan nama	 she created a religious endowment in the name of Sri Gopalji and appointed her mother in law Sheo Kuer as a shebait. Respondents 1 and 2	 claiming to be reversioners	 filed suit No. 16 of 1956 in the court of the First Subordinate Judge	 Gaya	 for a declaration that the two deeds were void and illegal and were not binding on their reversionary interest. Kachnar Kuer was defendant 1	 the adopted son was defendant 2 and Sheo Kuer was defendant 3 to the suit. During the suit	 the defendants were evidently of one mind and they contended by their written statements that the impugned deeds were executed under the authority given by the deceased Trilok Prasad Singh and that respondents 1 and 2 had no right to bring the suit after June 17	 1956 when the came into force The trial court dismissed the suit holding that Trilok Prasad Singh had given authority to Kachnar Kuer to make an adoption and to create an endowment and therefore both the deeds were valid. Against the dismissal of their suit	 respondents 1 and 2 filed First Appeal No. 152 of 1959 in the High Court of Patna. By its judgment dated October 3	 1964 the High Court allowed the appeal and decreed the suit holding that Trilok Prasad Singh had not given authority to Kachnar Kuer to take a son in adoption and under the Banaras School of Hindu Law by which the parties were governed	 an adoption made by a widow without the authority of her husband was invalid. The High Court also held that Trilok Singh had not authorised Kachnar Kuer to create a religious endowment over any part of his property and since by the Arpan nama a large piece of property was dedicated to the deity the dedication was void. On the question whether	 after the coming into force of the 	 respondents 1 and 2 as reversioners could maintain the suit	 the High Court held that on the material date Kachnar Kuer was not in possession of the property and therefore her limited estate could not ripen into an absolute estate under the . Kachnar Kuer made an application to the High Court for a certificate of fitness to appeal to this Court and the High Court by its order dated May 10	 1965 granted a certificate of fitness under Article 133(1) (b) of the Constitution. But after the petition of appeal was lodged in this Court	 Kachnar Kuer joined hands with respondents 1 and 2 and purported to enter into a compromise dividing the 1004 property left by Trilok Prasad Singh between themselves. The appellant	 Sheo Kuer	 who was appointed as a shebait under the deed of Arpan nama has thereafter	 obtained special leave to appeal to this Court from the judgment of the High Court. We are	 in this judgment	 concerned with Sheo Kuer 's appeal	 not with the appeal filed by Kachnar Kuer by certificate. The High Court has rejected the evidence led to show that 'Trilok Prasad Singh had given authority to Kachnar Kuer to make an adoption to him. The finding that the adoption is without the authority of the husband and therefore void is not challenged before us either by Kachnar Kuer or by the adopted son and that finding must there. fore be confirmed. Since the evidence on the other question as to whether Trilok Prasad Singh had given authority to Kachnar Kuer to create a religious endowment was closely linked with the question regarding the authority to adopt and since the pattern of evidence on both the questions is identical	 the High Court held that Kachnar Kuer did not either have the authority of her husband to instal the deity or dedicate any 1 property to the deity. This finding is not challenged before us by Sheo Kuer	 the shebait appointed under the Arpan nama	 and therefore we must proceed on the basis that the dedication was created by Kachnar Kuer without the authority of her husband. The point involved for determination in the appeal thus relates to the powers of a Hindu female on whom property has devolved upon the death of her husband	 to alienate the property for religious purposes. This question has been the subject matter of several decisions Of the Indian High Courts as also of the Judicial Committee. These decisions	 beginning with one of the earliest pronouncements on the subject in Collector of Masulipatam vs Cavly Vencata	 upto the decision of this Court in Kamala Devi vs Bachu Lal Gupta have been discussed with fullness and clarity of Mr. Justice Bijan Kumar Mukherjea in his Tagore Law Lectures on the Hindu Law of Religious and Charitable Trust. It is unnecessary to analyse the various Decisions which the learned author has considered because the true position on the subject is crystalised in the decision in Kamala Devi 's case. The law must now be taken as well settled that a Hindu widow possessing a widow 's estate cannot alienate the property which has devolved on her except for special purposes. To support an alienation for purely worldly purposes she must show necessity but she has a larger power of disposition for religious and charitable purposes or for Those purposes which are supposed to conduce to the spiritual` welfare of her husband. As pointed out by the Privy Council in Sardar Singh vs Kuni Behari	 the Hindu system recognises two sets of religious acts: those which are considered as essential for the salvation of the soul of the deceased and others which	 though not essential or obligatory	 are still pious observances which conduce to the bliss of the . deceased 's soul. The powers of a Hindu female to alienate property are wider in respect of acts which conduce to the spiritual benefit of 1005 her deceased husband. The widow is entitled to sell the property	 even the whole of it	 the income of the property is not sufficient to cover the expenses for such acts. In regard to alienations for pious observances	 which are not essential or obligatory	 her powers are limited to alienating only a small portion of the property. Applying the principles accepted in Kamala Devi 's case	 the simple question for decision	 in view of the fact that the Arpan nama was executed for a merely pious purpose and not for an essential or obligatory purpose is whether the alienation effected by Kachnar Kuer in favour of the deity is of a reasonable portion of her husband 's property. Respondents 1 and 2	 in paragraph 7 of their plaint	 passingly mentioned that Kachnar Kuer had transferred "a considerable portion" of the properties left by her husband. In paragraph 13 of the written statement which Kachnar Kuer filed on behalf of herself and her adopted son	 it was stated that in view of the fact that Trilok Prasad Singh had left about 150 Bighas of land	 the alienation of about 30 Bighas in favour of the deity could not be said to be unreasonable or excessive. One hundred and fifty Bighas are treated in the area as roughly equal to 90 acres so that 30 Bighas come to about 18 acres. Whether the alienation for a pious purpose is of a reasonable portion of the property must necessarily depend upon the total extent of the property which has devolved upon the widow. The mere circumstance that a 100 acres are alienated by the widow for a pious purpose will not justify the setting aside of the alienation on the ground that 100 acres is large property. The High Court	 without adverting to the fact that the widow had alienated only a one fifth portion of the property which had devolved upon her	 held that "a dedication of a large part of the property	 more than 18 acres of land	 cannot be defended on the part of a holder of a widow 's estate ". This is all that the High Court has to say on the point and obviously	 what it has said is not enough or relevant for invalidating the alienation. Whether the alienation is of a reasonable portion of the property is not a matter to be decided on precedents because what is reasonable must depend upon the facts and circumstances of each case. But an alienation of a one fifth portion cannot be said to be unreasonable or excessive. The finding of the High Court must therefore be set aside and along with it its judgment allowing the reversioner 's appeal and decreeing their suit. We therefore hold that the Arpan nama executed by Kachnar Kuer in favour of the deity is lawful and valid. In the result we allow the appeal	 set aside the judgment of the High Court and direct that the suit filed by respondents 1 and 2 shall stand dismissed with costs. S.R. Appeal allowed.

Kachnar Kuer	 on whom the property of her late husband devolved	 executed two registered deeds. By one of these she adopted a son to her deceased husband and by the other	 a deed of Arpan nama she created a religious endowment in the name of Shri Gopalji	 appointing her mother in law Sheo Kuer	 the appellant as the shebait. The respondents claiming to be the reversioners filed a suit for declaration that the two deeds were void	 illegal and not binding on their reversionary interest. That suit was dismissed on the ground that the late husband of Kachnar Kuer had given authority to her to make an adoption and to create an endowment. On appeal	 the High Court reversed the findings of the trial court and decreed the Suit. The High Court however	 granted a certificate of fitness ' under article 133(1)(b) of the Constitution and since after obtaining the certificate	 Kachner Kuer purported to compromise the suit with the reversioners	 Sheo Kuer	 the shebait came up in appeal by special leave. Allowing the appeal	 ^ HELD. (i) It is well settled that a Hindu widow possessing a widow 's estate cannot alienate tho property which has devolved on her except for special purposes.
