A bird in flight in the sky needs two wings; a person on the earth below needs two legs to move; an aspirant eager to attain the mansion of moksha (liberation), the abode of freedom, needs renunciation and wisdom - renunciation of worldly desires and wisdom to become aware of the Atma. When a bird has only one wing, it cannot rise up into the sky. In the same manner, if one has only renunciation or only wisdom, one cannot attain the supreme Self, Brahman. The sense of “mine” is the bond of deluding attachment. How long can one cling to what one fondles as mine? Some day, one has to give up everything and leave, alone and empty handed. This is the inescapable destiny.

- Sutra Vahini, Chap 1 "Renouncing Me and Mine".

Love is the solvent for the hardest of the hearts.  - Baba
