prāṇānāṃ prāṇanaṃ spandastacchāntau te dṛṣatsamāḥ ,
yataḥ sthitā dhāraṇayā tenānaṣṭāsya sā tanuḥ 56

56. spandaḥ prāṇānām prāṇanam tat śāntau te dṛṣatsamāḥ yataḥ dhāraṇayā sthitā,

56. The pulsation (spanda) is the very life-breath (prāṇana) of the vital energies (prāṇa). When that pulsation is calmed, those vital energies become like rocks. Because they are held firm by concentration (dhāraṇā), that body (tanu) does not perish due to that.
