That chair is maya. That table is maya. A physicist will tell you they’re 99% pure space. In other words, they’re 1% form and 99% name. Maya makes you pound the table and feel it also. For the body-mind is 99% name as well.
The antahkarana (the inner instrument) is comprised of buddhi, manas, and ahankara (intellect, mind, ego). The ego and the mind have this symbiotic relationship born out of ignorance (avidya). Neither listens to the intellect, that reflection of pure intelligence (cit).
In jnana maya yoga, self-realization begins with intelligent self-inquiry. Self-inquiry begins with the satguru finally getting through, by means of instinct, intuition, or revelation. All are tattvamasi. Only the decibels differ.

In maya, there’s three bodies (causal, subtle, gross) and five sheaths. Of the five, the subtle body consists of vijnanamaya (intelligence), manomaya (mind), and pranamaya (life force).
On the other hand, the inner instument consists of intellect, mind, and ego. It appears ego is the mind usurping the life force.
In a functional subtle body, the mind provides the data, and the intellect makes the decision. And the life force moves the body in perfect nondoing.
