What are the relations between Tridevs and Tridevis?

[A question by Shri Jayesh Pandey]

Swami replied:- The triad of the forms of God represents the creator, the maintainer and the destroyer of the creation. The triad of the forms of Goddess represents the creator mediated by a part of the creation representing the power of the creator, the maintainer and the destroyer of the creation. The possessor of power and the power are one and the same in the essential meaning. We can’t say whether the unimaginable God is the possessor of power or the power. He can be either or and can be both as well in the unimaginable state. Only when the unimaginable God is mediated, we can say God Brahma as the possessor of power of creation and Goddess Sarasvati as the power of creation. We should be very careful and systematic in using these words.
