Having conquered the mind, for the peaceful one, establishment in the foremost soul,
In cold, heat, pleasure, pain, honor, dishonor.

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.

For one who has conquered the mind, the Supersoul is already reached, for he has attained tranquility. To such a man happiness and distress, heat and cold, honor and dishonor are all the same.
