The agony caused by the longing to see God is not sorrow; it is bliss. The state that we attain by calling and crying to God is equal to the bliss that the yogi experiences in samadhi.
Love is the very foundation, beauty and fulfillment of life. If we dive deep enough into ourselves, we will find that the one thread of universal love ties all beings together. As this awareness dawns within us, peace alone will reign.
Devotion is not a mental weakness. Neither is it only the first step, but something like the substratum for attaining the goal.
