In the cultivation of knowledge there are two kinds of transcendentalists. One of them worships the impersonal Brahman, and the other desires liberation. Since monists worship the impersonal feature of Brahman, they are therefore called worshipers of Brahman. These Brahman worshipers are further divided into three categories: the neophyte, one who is absorbed in Brahman realization, and one who has actually realized himself as Brahman. If devotional service is added, the knower of Brahman can then become liberated; otherwise there is no possibility of liberation. Anyone who is fully engaged in devotional service in Kṛṣṇa consciousness is understood to be already realized in Brahman. Devotional service is so strong that one is attracted to Kṛṣṇa even from the platform of Brahman worship. The Lord awards the devotee the perfection of a spiritual body, and he eternally engages in the transcendental service of Kṛṣṇa. It is when the devotee understands and becomes attracted by Kṛṣṇa's transcendental qualities that he wholeheartedly engages in devotional service. For instance, the four Kumāras and Śukadeva Gosvāmī were liberated from the beginning, yet in their later life they became attracted to the pastimes of Kṛṣṇa and became devotees. Sanaka Kumāra was attracted by the aroma of the flowers offered to Kṛṣṇa, and the other Kumāras were attracted by the transcendental qualities of the Lord and thus engaged in His devotional service. The nine mystics mentioned in the Eleventh Canto of Śrīmad-Bhāgavatam are understood to have been transcendentalists from birth by virtue of hearing of the transcendental qualities of Kṛṣṇa from Brahmā, Lord Śiva and Nārada.
Sometimes one becomes attracted to Kṛṣṇa and His transcendental qualities simply by looking upon the beautiful features of His transcendental body, in which case one abandons the desire for liberation and engages in His devotional service. The devotee regrets his loss of time in the so-called cultivation of knowledge and becomes a pure devotee of the Lord.
