From Essence of Devi Bhagavata Purana hosted on kamakoti website:
Maha Vishnu remote-controlled by Devi Bhagavati:
In the Introductory Recitation of Devi Bhagavatam, Sage Suta quoted Narada Maharshi as having confirmed by Lord Vishnu Himself to Lord Brahma that His own Premordial Energy of Universal Existence is the result of Her empowerment to Maha Vishnu to execute Her commands! Maha Vishnu reiterated that He is subservient to Devi Bhagavati and is always in Her Tapasya or meditation, but at the same time, enjoys freedom to possess the company of Goddess Lakshmi, to incarnate Himself in various forms and features some times as Dasavataras as Fish, Tortoise, Boar, Man-Lion, Dwarf, Rama, Parasurama, Krishna, Buddha or Kalki; some times as Mohini to distribute ‘Amrit’ or Nectar and so on. But His actions are always remote-controlled and are oriented to protect the Virtuous and punish the Wicked. Thus Maha Vishnu is indeed the Highest Representative of Maha Devi with full freedom to act on His own, within the framework of Her Supreme Control.
Can someone produce the relevant passages from Devi Bhagavatam? How can one be remote controlled and at the same time have full freedom? That seems contradictory.
