So about the expansions of Lord Kṛṣṇa, in Brahma-saṁhitā, Īśopaniṣad, and there are various Vedic literatures... They are all taken together, calculated and presented by Lord Caitanya. He says,
- svayaṁ-rūpa tad-ekātma-rūpa, āveśa-nāma
- prathamei tina-rūpe rahena bhagavān
Svayaṁ-rūpa, the Supreme Personality of Godhead Himself, He is called svayaṁ-rūpa, His personal feature. Then tad-ekātmā. Tad-ekātma-rūpa means not exactly the same person, but almost the same. Tad-ekātma-rūpa. And āveśa. Āveśa means that empowered. There is always difference between the individual soul and the Supreme Absolute Soul. When the individual soul is specially empowered by the Supreme Soul, that is called āveśa. He can act almost like God. We accept, according to this āveśa, āveśa-avatāra incarnation, authorized incarnation, we accept, my Guru Mahārāja accepted Lord Jesus Christ and Hazrat Muhammad, this āveśa incarnation, almost the same power.
