Samadhisattva 禪定尊 / 三摩地尊

The samadhisattva (Skt.; Tib. ཏིང་་ངེ་འཛིན་སེམས་དཔའ་, Wyl. ting 'dzin sems dpa)―meditative concentration form or being―when practising in an elaborate way is the life-force seed syllable, the very essence of the deity, visualized in the heart centre of the jñanasattva―the wisdom being―in the heart centre of oneself visualized as the samayasattva―the commitment being, which is encircled by the mantra garland. It is the innermost of the three sattvas. When practising in a simple way it is visualized within the heart centre of the samayasattva.
