In the Bhagavad-gita, mad-dhama ("My abode") is mentioned several times, and according to the version of the Supreme Personality of Godhead Sri Krsna there exists the unlimited spiritual sky, wherein the planets are called Vaikunthas, or the abode of the Personality of Godhead. In that sky, which is far, far beyond the material sky and its sevenfold coverings, there is no need of the sun or the moon, nor is there necessity of electricity for illumination, because the planets are self-illuminating and more brilliant than the material suns. pure devotees of the Lord are absolutely in harmony with the Personality of Godhead, or in other words, they always think of the Lord as their only dependable friend and well-wisher. They do not care for any mundane creature, up to the status of Brahma, the lord of the universe. Only they can definitely have a clear vision of the Vaikuntha planets. Such pure devotees, being perfectly directed by the Supreme Lord, do not create any artificial perplexity in the matter of transcendental understanding by wasting time in discussing what is Brahman and what is non-Brahman, or maya, nor do they falsely think of themselves as one with the Lord, or argue that there is no existence of the Lord separately, or that there is no God at all, or that living beings are themselves God, or that when God incarnates Himself He assumes a material body. Nor do they concern themselves with many obscure speculative theories, which are in actuality so many stumbling blocks on the path of transcendental understanding. Apart from the class of impersonalists or nondevotees, there are also classes who pose themselves as devotees of the Lord but at heart maintain the idea of salvation by becoming one with the impersonal Brahman. They wrongly manufacture their own way of devotional service by open debauchery and mislead others who are simpletons or debauchees like themselves. All these nondevotees and debauchees are, according to Visvanatha Cakravarti, duratmas, or crooked souls in the dress of mahatmas, or great souls. Such nondevotees and debauchees are completely excluded from the list of transcendentalists by the presentation of this particular verse by Sukadeva Gosvami.
