Yoga Sutra 1.37 meditation on freedom from passion

Sūtra I.37

Or on a mind whose meditation is on freedom from passion

He from whose thinking all passion has gone, is free from passion, namely dispassionate. It is well known what dispassion is: there must be freedom from desire even in the case of a naturally passionate man in the presence of objects of desire, for instance women or possessions. Let him practise with this idea in mind. But actual objects should not be part of the meditation, because of the evils in them. Thus coloured by meditation on a mind free from passion, the mind of the yogin attains steadiness. For a mind, once the bridle of passion has been set on it, runs like a horse driven by another.
