Radharani is the expansion of Krishna. Krishna is the energetic and Radharani is the energy.To promulgate prema-bhakti [devotional service in love of Godhead], Krishna appeared as Sri Krishna Caitanya with the mood and complexion of Sri Radha.
Chanting Hare Krishna increases the ocean of transcendental bliss. What keeps us bound to this world is our very deep rooted tendency to take credit for the good we do, to take credit for the good that we don’t do, and to give blame for the bad that we do.
Everything is produced by Him. We simply offer everything to the Lord to show our love and gratitude towards him.
