Planets such as Indraloka and Candraloka are meant for the heavenly enjoyment of the most pious fruitive workers. The highest four planets, however, Satyaloka, Maharloka, Janoloka and Tapoloka, are meant for those who are most perfectly endeavoring for liberation. Caitanya MahÄprabhu is so inconceivably merciful that He is promoting the most fallen victims of Kali-yuga beyond these four planets and even beyond Vaikuṇá¹ha, to the supreme planet of Lord Kṛṣṇa in the spiritual sky, called Goloka Vá¹›ndÄvana. ÅšrÄ«la BhaktisiddhÄnta SarasvatÄ« ṬhÄkura explains that heaven is the residence of the demigods, the earth is the residence of the human beings, and in between is a temporary residence for both classes of beings.
