From him the Ṛg, Sāma, Yajur, initiation, sacrifice, ritual, animals, all beings, inhalation and exhalation, rice and barley, austerity, truth, vow, regulation, Vedas, sacrifice —from him, from him.
Fourth repetition, extending the liturgy. In our yoga practice, this insistence may seem excessive, but it has a purpose: to carry the mind beyond literal meaning toward resonant vibration. Words become mantra, concepts dissolve into presence. The vidhāna (regulation/order) included in the list reminds us that even the structure of the universe is emanation of Reality, not something imposed from outside. Everything is tasmāt —from Him, from Him.
