6.116

Or three dharmas are taken as medicine, which are calming, contemplation, and morality that accords with the path, protecting spontaneously. Furthermore, the three samādhis: entering emptiness from the provisional is called śūnyatā-samādhi; not seeing the characteristics of emptiness is called animitta-samādhi; the cessation of the karma of birth and death is called apraṇihita-samādhi.
