Caitanya Mahaprabhu teaches us that we should only beg God for His service life after life. This is the actual meaning of the Hare Krsna maha-mantra. When we are chanting Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare / Hare Rama, Hare Rama, Rama, Rama, Hare Hare, we are actually addressing God and His energy, Hara. Hara is Krsna’s internal potency, Srimati Radharani or Laksmi. Jaya radhe! This is daivi prakrti, and the devotees take shelter of the daivi prakrti, Srimati Radharani. Thus the Vaisnavas worship Radha-Krsna, Laksmi-Narayana and Sita-Rama. In the beginning of the Hare Krsna maha-mantra we first address the internal energy of Krsna, Hare. Thus we say, “O Radharani! O Hare! O energy of the Lord!”
