One does not have to leave anything but the Doshas such as Kaama, Krodha, Moha, selfish attachments, jealousy, ungratefulness etc. Samnyasa, Tyaga, detachment, NKY, or any progress in spiritual life is not possible if one thinks oneself as the owner or the doer. Do not grieve. Daily reading of even few verses of the Holy Gita will recharge you both physically and spiritually. No other person shall do a more pleasing service to Me, and no one on the earth shall be more dear to Me.
Ignorance is the mother of all sins.
The giving of the gift of knowledge is the best charity. The ignorance of metaphysical knowledge is humanity's greatest predicament. The best welfare is to help others discover their real nature that is the source of everlasting peace and happiness rather than provide material goods and comforts for temporary happiness.
