What are the basic teachings of Śrī Chaitanyadeva?

Sri Hari is the Supreme Absolute Truth. He is Omnipotent. He is the nectarean ocean of transcendental mellows. The living entities are His separated parts and parcels. The condiitoned souls are controlled by māyā, whereas the librated souls are free from māyā. Both the spiritual and material worlds are simultaneously one with and different from Sri Hari. Devotional service is the only way to obtain the goal of life, and the love of God is the ultimate goal of life.
