Bhagavad Gita Chapter 11
Conclusion:
Love must flow from our being. Love happens when we experience cosmic consciousness, when we have a spiritual experience, when our ego disappears. Krsna lays out the whole technique for us, step-by-step. After a spiritual experience, so much gratitude flows from our being, so much love overflows from our being, that we start radiating it. We need not make an effort, it just flows. We cannot stop it. No one can show or experience love unless they have had a spiritual experience.
