Brahma is traditionally called "The Creator," the personification of rajas guna, but MAPI seems to be saying that Sattva (personified by Vishnu, traditionally termed "The Maintainer") is responsible for creation:

Sattva in the Universe is responsible for Creation. Inside our own self, it gives us the ability to visualize well, think right, do good and act in accordance with the laws of nature. Rajas stands for action. In cosmic terms, Rajas is responsible for Maintenance and Nurturing of what has been created. In human beings, the Rajasic guna or quality means giving a concrete shape to dreams, being motivated and taking action. Excess of Rajas, however, leads to an unsettled and perpetually restless mind. Tamas supplies us with the ability to finish or complete what was generated by Sattva and Rajas. In the context of the Universe, Tamas stands for Destruction. While some may see Tamas as a negative guna, ayurvedic philosophy says Tamas has its own role in the scheme of things. It weans us from the old and the lifeless, urging us to move on and invest in that which is still alive.
