Here it is clearly mentioned that meditation, which is an action of the mind, is not the perfect stage of samādhi, or absorption. In the beginning the mind is employed in attracting the form of the Supreme Personality of Godhead, but in the higher stages there is no question of using the mind. A devotee becomes accustomed to serving the Supreme Lord by purification of his senses. In other words, the yoga principles of meditation are required as long as one is not situated in pure devotional service. The mind is used to purify the senses, but when the senses are purified by meditation, there is no need to sit in a particular place and try to meditate upon the form of the Lord. One becomes so habituated that he automatically engages in the personal service of the Lord. When the mind forcibly is engaged upon the form of the Lord, this is called nirbīja-yoga, or lifeless yoga, for the yogī does not automatically engage in the personal service of the Lord. But when he is constantly thinking of the Lord, that is called sabīja-yoga, or living yoga. One has to be promoted to the platform of living yoga.
One should engage in the service of the Lord twenty-four hours a day, as confirmed in the Brahma-saṁhitā. The stage of premāñjana-cchurita can be attained by developing complete love. When one’s love for the Supreme Personality of Godhead in devotional service is fully developed, one always sees the Lord, even without artificially meditating on His form. His vision is divine because he has no other engagement. At this stage of spiritual realization it is not necessary to engage the mind artificially. Since the meditation recommended in the lower stages is a means to come to the platform of devotional service, those already engaged in the transcendental loving service of the Lord are above such meditation. This stage of perfection is called Kṛṣṇa consciousness.
