- vadanti tat tattva-vidas
- tattvaṁ yaj jñānam advayam
- brahmeti paramātmeti
- bhagavān iti śabdyate
- (SB 1.2.11)
So, the Absolute Truth is realized in three different features, according to the capacity of realization of the person. Those who are trying to approach the Absolute Truth by exercise of the senses, they can reach up to the point of impersonal Brahman. Those who are searching out the Absolute Truth by meditation, by mystic yogic practices, they can realize the Paramātmā feature of the Absolute Truth. And those who are engaged in devotional service, they realize the Absolute Truth as the Supreme Personality of Godhead.
Actually, we have to reach to the point of Personality of Godhead, person. Before that, Brahman realization and Paramātmā realization, that is partial realization of the Absolute Truth, because Kṛṣṇa says in the Bhagavad-gītā, brahmaṇaḥ ahaṁ pratiṣṭhā (BG 14.27). The impersonal Brahman is resting on Kṛṣṇa. Just like the sunshine.
Sunshine is very all-embracing, wide, widely spread all over the universe, the sunshine. But the sunshine is resting on the sun globe. We see the sun globe, localized. It is floating in one corner of this universal sky. But the sunshine is covering the whole universe. That does not mean the sunshine is more important than the sun globe.
