7. The sun is situated almost in the center of each and every universe, and it distributes profuse light and heat all over the universe. There are millions and billions of suns in all the millions and billions of universes within the  mahattatva . The suns and moons are required within the universes because they are dark by nature. The  Vedas  instruct us to go out of the dark universes and reach the glowing effulgence, the  brahmajyoti .
8. The  brahmajyoti  is due to the illuminating Vaikuṇṭha planets, which need no sun or moon or power of electricity.
Śrīmad-Bhāgavatam  helps us reach the supreme planet, Goloka Vṛndāvana. The door is open for everyone. Human life is meant for this particular aim, for it is the highest perfection.
His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda  first met his spiritual master, Śrīla Bhaktisiddhānta Sarasvatī Gosvāmī Mahārāja, in Calcutta in 1922. Śrīla Bhaktisiddhānta liked this educated young man and injected in his idea of preaching the message of  Śrīmad-Bhāgavatam  all over the world. At Allahabad in 1933 Śrīla Prabhupāda became his formally initiated disciple, and in 1937, just days before Śrīla Bhaktisiddhānta's departure from this mortal world, he was specifically ordered to spread Kṛṣṇa consciousness in the English language. Thus in 1944 Śrīla Prabhupāda started  Back to Godhead  magazine, which is now circulated in six different languages throughout the world, and he also published, in English, the first three volumes of his  Śrīmad-Bhāgavatam .
In 1965, at the advanced age of 70, His Divine Grace sailed to the United States to fulfill his master's sacred mission, bringing with him only seven dollars, some books and a pair of hand cymbals. Shortly afterwards he began classes on  Bhagavad-gītā  in a small storefront in New York City. Now, only six years later, Śrīla Prabhupāda's International Society for Krishna Consciousness, with more than seventy centers in major cities throughout the world, has become an important institution of spiritual knowledge and culture, and Śrīla Prabhupāda's authoritative translations, commentaries and summary studies of Vedic literature have become standard textbooks of transcendental science.
