Desire binds you and makes you restless. Even by desiring enlightenment, you bind yourself. To know Truth, you must be without desire.
Ironically, you’d die without desire! Your subconscious mind by its very nature desires to keep you alive! So what does it mean to be “without desire” practically speaking? To desire and act selflessly.
Selfless action or serving others doesn’t trigger in you another infinite cycle of merciless cause and effect (karma) – because pure, selfless desire and action have no expectation whatsoever – thus you can’t be disappointed, regardless of the result. But even better, you ARE rewarded: when you make someone happy, you see it in their face and you feel happy too.
“The more you serve, the more happiness you enjoy. Such a person knows the secret of life.” – Sri Swami Satchidananda
