When the individual soul and the Supreme Being attain the same essence, and all mental intention is destroyed, that is called samādhi.

This verse offers a precise definition of samādhi from the perspective of tantric yoga:

Samarasatva — literally “same flavor” or “same essence.”The two (jīvātman and paramātman) who seemed different reveal their essential identity.It’s not that they become the same;they always were.

Jīvātman — the individual soul, the sense of being a separate entity.Paramātman — the supreme Being, the universal consciousness.

Praṇaṣṭa-sarva-saṅkalpa — destruction of all intentions or resolutions.Saṅkalpa is the formative activity of the mind: planning, desiring, imagining.In samādhi, this activity ceases completely.

The Bihar School points out that this does not imply mental death but transcendence of the conditioned mind.Consciousness remains, but free from the fluctuations of thought.

Mallinson notes that this definition combines Vedāntic elements (ātman-brahman identity) with the yogic terminology of Patañjali (cessation of mental fluctuations).
