Srimad Bhagavatam 11.24.11-12 - The Growth of Bhakti Lata is Depend on our Sadhana (download mp3)
by Shivram Prabhu at ISKCON Chowpatty
so ’sṛjat tapasā yukto
lokān sa-pālān viśvātmā
bhūr bhuvaḥ svar iti tridhā
Lord Brahmā, the soul of the universe, being endowed with the mode of passion, performed great austerities by My mercy and thus created the three planetary divisions, called Bhūr, Bhuvar and Svar, along with their presiding deities.
devānām oka āsīt svar
bhūtānāṁ ca bhuvaḥ padam
martyādīnāṁ ca bhūr lokaḥ
siddhānāṁ tritayāt param
Heaven was established as the residence of the demigods, Bhuvarloka as that of the ghostly spirits, and the earth system as the place of human beings and other mortal creatures. Those mystics who strive for liberation are promoted beyond these three divisions.
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 Mahāprabhu is so inconceivably merciful that He is promoting the most fallen victims of Kali-yuga beyond these four planets and even beyond Vaikuṇṭha, to the supreme planet of Lord Kṛṣṇa in the spiritual sky, called Goloka Vṛndāvana. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura 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.
