There is no heaven or hell or liberation... nothing but the Self in this expanded cosmic consciousness.
It is bondage when the mind desires or grieves at anything, rejects or accepts anything, feels happy or angry at anything.
The renunciation of desire alone is renunciation of the world.
Non-attachment for sense-objects is liberation: love for sense-objects is bondage.
Bondage consists only of desire, and the destruction of desire is liberation.
