It is a great falldown on the part of the impersonalists to think that the Supreme Lord appears within a material body and that one should therefore not meditate upon the form of the Supreme but should meditate instead on the formless. For this particular mistake, even the great mystic yogīs or great stalwart transcendentalists also come back again when there is creation.

By perfecting their yogic practice, yogīs can reach the highest planet, Brahmaloka, or Satyaloka, and after giving up their material bodies, they can enter into the body of Lord Brahmā. Because they are not directly devotees of the Lord, they cannot get liberation directly. They have to wait until Brahmā is liberated, and only then, along with Brahmā, are they also liberated.

The spiritual sky is called avyākṛta, that which does not change, and there the Supreme Personality of Godhead resides. When, after ruling over the material universe under the influence of the time element, Lord Brahmā desires to dissolve it and enter into the kingdom of God, others then enter with him.

Persons who are worshipers of Hiraṇyagarbha, the plenary expansion of the Supreme Personality of Godhead Garbhodakaśāyī Viṣṇu, do not directly approach the Supreme Personality of Godhead in Vaikuṇṭha. They remain within this universe on Satyaloka or other higher planets until the end of the life of Brahmā. Then, with Brahmā, they are elevated to the spiritual kingdom.

The illuminated path is devotional service. It is advised in the Vedas not to pass through the darkness, but to pass through the sun planet. It is also recommended here that by traversing the illuminated path one can be freed from the contamination of the material modes of nature; by that path one can enter into the kingdom where the completely perfect Personality of Godhead resides.

There are two kinds of religious performances. One is the religious activities performed for elevation to higher planets or for economic prosperity, the final aim of which is sense gratification. But the opposite type of religious performance, is to act for the Supreme Personality of Godhead.

Arjuna was a kṣatriya, and his occupational duty was to fight. Generally, kings fight to extend their kingdoms, which they rule for sense gratification. But as far as Arjuna is concerned, he declined to fight for his own sense gratification. He said that although he could get a kingdom by fighting with his relatives, he did not want to fight with them. But when he was ordered by Kṛṣṇa and convinced by the teachings of Bhagavad-gītā that his duty was to satisfy Kṛṣṇa, then he fought.

The materially attached are very eager to promote themselves to the heavenly planets such as the moon. There are many heavenly planets to which they aspire just to achieve more and more material happiness by getting a long duration of life and the paraphernalia for sense enjoyment. But the attached persons do not know that even if one goes to the highest planet, destruction exists there also.

The moon is considered one of the planets of the heavenly kingdom. One can be promoted to this planet by executing different sacrifices recommended in the Vedic literature, such as pious activities in worshiping the demigods and forefathers with rigidity and vows. But one cannot remain there for a very long time. Life on the moon is said to last ten thousand years according to the calculation of the demigods.
