If you open the door to the magnetic power of friendship, souls of like vibrations will be attracted to you.

The way to liberation lies through this realization of the Self, by God-communion and by remaining in this God-aware state of the soul while performing dutiful actions. Any individual can reach this supreme actionless state by the renunciation of all fruits of actions: performing all dutiful acts without harbouring in his heart any likes and dislikes, possessing no material desires, and feeling God, not the ego, as the Doer of all actions.
