The influence of material nature cannot harm an enlightened being, even if he indulges in material acts, because he knows the truth about the Absolute, and his mind remains fixed on the Supreme Personality of Godhead.
When a person thus devotes himself to devotional service and spiritual realization for many years, in many lifetimes, he becomes quite unwilling to enjoy the pleasures offered by any material planet, even the highest one, known as Brahmaloka; his consciousness then becomes fully developed.
My devotee verily attains spiritual realization through My infinite and causeless grace, and thus, freed from all doubt, he marches steadily towards his own destination, which is directly under the protection of My spiritual energy, all pure bliss. This is the ultimate perfection that the individual must attain. After leaving his material body, the spiritualist therefore returns to that absolute abode, never to return to this world.
When the attention of the perfect spiritualist is no longer captivated by the feats that supernatural powers, these manifestations of external energy, allow to be accomplished, his progress towards Me knows no limits, so much so that death has no more hold on him.
The Supreme Lord, Kapila said:
My dear mother, daughter of a king, I shall now explain to you the path of yoga, which is the concentration of the mind. By this practice, one becomes joyful and progresses step by step on the path of the Absolute Truth.
One should perform one's prescribed duties to the best of one's ability and avoid those that are not assigned to one. One should be satisfied with what comes by the grace of the Lord, and worship the lotus feet of a spiritual master.
One should stop indulging in conventional religious practices and be attracted only by those that lead to salvation. One should eat very frugally and always live in solitude so as to attain the highest perfection of existence.
One should practice non-violence and truthfulness, not steal, and possess only what is necessary for one's subsistence. In addition, one should abstain from sexual activity, practice austerity and purity, study the Vedas, and worship the Supreme Form of Godhead, the Supreme Personality of Godhead.
One should observe silence, acquire constancy through the practice of the various yoga postures, control the circulation of the vital air, detach the senses from their objects, and then concentrate the mind on the heart.
