There are two kinds of liberated souls having material bodies: the soul liberated by devotional service and the soul liberated by the cultivation of knowledge. The liberated soul in devotional service, attracted by the transcendental qualities of Kṛṣṇa, becomes more and more elevated, whereas those who engage in dry speculation and simply cultivate knowledge without devotion fall due to their many offenses. This is confirmed in Śrīmad-Bhāgavatam (10.2.32) where it is stated:
- ye 'nye 'ravindākṣa vimukta-māninas
- tvayy asta-bhāvād aviśuddha-buddhayaḥ
- āruhya kṛcchreṇa paraṁ padaṁ tataḥ
- patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ
"O Lord, the intelligence of those who think themselves liberated but who have no devotion is not pure. Even though they rise to the highest point of liberation by dint of severe penances and austerity, they are sure to fall down again into this material existence, for they do not take shelter at Your lotus feet." This is also confirmed in Bhagavad-gītā:
- brahma-bhūtaḥ prasannātmā
- na śocati na kāṅkṣati
- samaḥ sarveṣu bhūteṣu
- mad-bhaktiṁ labhate parām
"One who is transcendentally situated at once realizes the Supreme Brahman. He never laments nor desires to have anything; he is equally disposed to every living entity. In that state, he attains pure devotional service unto Me." (BG 18.54)
Thus one who is actually situated in Brahman realization has no reason to lament or desire. He is equal to everyone and is thus eligible for devotional service. This was also accepted by Bilvamaṅgala Ṭhākura, who, in his later life, lamented: "I was situated as a monist in order to become one with the Supreme, but somehow or other I contacted a naughty boy and became His eternal servitor." In other words, those who attain self-realization by the execution of devotional service attain a transcendental body, and, being attracted to the transcendental qualities of Kṛṣṇa, engage fully in pure devotional service.
Anyone who is not attracted to Kṛṣṇa is understood to be still under the spell of the illusory energy (māyā), but one who is attempting to be liberated by the process of devotional service is actually liberated from the spell of māyā. In the Eleventh Canto of Śrīmad-Bhāgavatam there are many instances recorded of devotees who became liberated in this life simply by engaging in devotional service.
