The mind acts like an enemy for those who do not control it.

One who has control over the mind is tranquil in heat and cold, in pleasure and pain, and in honor and dishonor; and is ever steadfast with the Supreme Self.

With senses, mind, and intellect under control; having liberation as the prime goal; free from lust, anger, and fear; such a sage is verily liberated.

Discrimination, knowledge, non-delusion, forgiveness, truthfulness, control over the mind and senses, pleasure, pain, birth, death, fear, fearlessness; .

Delusion arises from anger. The mind is bewildered by delusion. Reasoning is destroyed when the mind is bewildered. One falls down when reasoning is destroyed.

A person is said to have achieved yoga, the union with the Self, when the perfectly disciplined mind gets freedom from all desires, and becomes absorbed in the Self alone.
