Bhagavad Gita states that the practice of meditation frees one from all afflictions.
The disunited mind is far from wise; how can it meditate?
How be at peace? When you know no peace, how can you know joy? When you let
your mind follow the call of the senses, they carry away your better judgment
as storms drive a boat off its charted course on the sea. Use all your power to
free the senses from attachment and aversion alike, and live in the full wisdom
of the Self. (Gita Chapter 2 verses 66 to 68)
Know that prakriti and purusha are both without beginning,
and that from prakriti come the gunas and all that changes. Prakriti is the
agent, cause and effect of every action, but it is purusha that seems to
experience pleasure and pain.
Purusha, resting in prakriti, witnesses the play of the
gunas born of prakriti.
But attachment to the gunas leads a person to be born good
or evil.
Within the body, the supreme Purusha is called the witness,
approver, supporter, enjoyer, the supreme Lord, the highest Self. Whoever
realizes the true nature of Purusha, prakriti and the gunas, whatever path he
or she may follow is not born separate again. (Gita Chapter 13 verses 19 to 23)
The practice of mediation frees one from all affliction.
This is the path of Yoga. Follow it with determination and sustained
enthusiasm. Renouncing wholeheartedly all selfish desires and expectation, as
your will to control the senses. Little by little through patience and repeated
effort, the mind will become stilled in the Self. (Gita Chapter 6 verses 23 to
24)
