A mind that is
A mind that is characterized by unrest will not be tranquil even in the presence of great calm.
If a person has a calm and stable mind, this influences his/her attitude and behavior in relation to others. In other words, if someone remains in a peaceful and tranquil state of mind, external surroundings can cause them limited disturbance.
If the mind is tranquil and occupied with positive thoughts, the body will not easily fall prey to disease.
Tranquil or calm abiding is a heightened state of awareness possessing a very single nature.

In the stage of perfection called trance, or samadhi, one’s mind is completely restrained from material mental activities by practice of yoga. This perfection is characterized by one’s ability to see the self by the pure mind and to relish and rejoice in the self. In that joyous state, one is situated in boundless transcendental happiness, realized through transcendental senses. Established thus, one never departs from the truth, and upon gaining this he thinks there is no greater gain. Being situated in such a position, one is never shaken, even in the midst of greatest difficulty. This indeed is actual freedom from all miseriesarising from material contact. (6.20-23)
The mind is charmed by distance. God is nearest to us, as he resides in us. Thus mind is not charmed by God.
The mind is its own creator, at every instant. Hence its responsibility, which is essential.
