The light inside and the light outside merge. Q. Well, Swami. You have said that the human being in this body composed of the five elements has to realise the Atma encased in the Panchakosa. A. Kosa means a sheath, a case, a cover. A sword is put into a scabbard.
Money is kept in a treasury or kosa.
You must realise that the thing kept in this five-fold case, is the real 'I'. To see one's own truth one has to remove the five cases, the Panchakosa. They are called the Annamaya, the Praanamaya, the Manomaya, the Vijnaanamaya and the Aanandamaya kosas. This body grew in the womb of the mother with the help of the Anna or Food taken by the mother. Besides, even after birth, it has grown and is being sustained by food alone.
