Samādhi Pāda · Sutra 37
वीतरागविषयं वा चित्तम्
vīta-rāga-viṣayaṃ vā cittam
Or [meditating on] a mind free from attachment.
Vīta-rāga means “free from passion, detached.” This sutra suggests taking as an object of meditation the mind of a being who has transcended attachment.
It may refer to contemplating the mind of a realized master, a saint, or a sage. By meditating on what a mind completely free of desire and aversion would be like, the practitioner begins to cultivate those same qualities.
It can also be interpreted as meditating on the state of one’s own mind when it is momentarily free of reactivity — using those moments of clarity as a model for practice.
