So,
- jñāna-śakty-ādi-kalayā
- yatrāviṣṭo janārdanaḥ
- ta āveśā nigadyante
- jīvā eva mahattamāḥ
Another definition is given by Sanātana Gosvāmī. This same Sanātana Gosvāmī who is now being taught by Lord Caitanya, he also has written many books. These two brothers, Rūpa Gosvāmī and Sanātana Gosvāmī, and their nephew, Jīva Gosvāmī, composed many valuable literatures. So Sanātana Gosvāmī has written one book, Laghu-bhāgavatāmṛtam. Laghu-bhāgavatāmṛtam, supplementary to Śrīmad-Bhāgavatam. So in that Laghu-bhāgavatāmṛtam book, he has written,
- jñāna-śaktya-ādi-kalayā
- yatrāviṣṭo janārdanaḥ
- ta āveśā nigadyante
- jīvā eva mahattamāḥ
He has defined that these śaktyāveśa avatāra, they are all living entities; they are not on the level of Viṣṇu-tattva. But they have special power and special, I mean to say, opulence to glorify the Supreme Lord.
- 'vibhūti' kahiye yaiche gītā-ekādaśe
- jagat vyāpila kṛṣṇa-śakty-ābhāsāveśe
Now that vibhūti is, is mentioned by Lord Caitanya. That vibhūtimat sattvam, śaktyāveśa, there are many, many... We find in the history so many extraordinary, powerful men come and go. They are called vibhūti of the Supreme Lord.
- yad yad vibhūtimat sattvaṁ
- śrīmad ūrjitam eva vā
- tat tad evāvagaccha tvaṁ
- mama tejo-'ṁśa-sambhavam
- Anyone extraordinary.
