We are like fish out of water. Just as a fish cannot be happy unless he is in the water, we cannot be happy apart from the spiritual world.
To the degree we cultivate the spirit of selfless service, to that degree we’ll actually find bliss in life.
The more we are happy in Krishna Consciousness the more we become purified.
Actual joy is a product of the spiritual nature. It spontaneously manifests when the living entity begins to love God.
