When we chant the Hare Krishna Maha Mantra, Hare refers to Haraa or Srimati Radharani. His Divine Grace A.C. Bhaktivedanta Swami Prabhupada has explained that Mother Haraa helps us to achieve the grace of the Supreme Father Hari, or Krishna. And The Lord reveals Himself to such a sincere devotee who has been recommended by Srimati Radharani.
