Chapter 9 · The Royal Secret · Krishna said
Bhagavad Gita 9.16 — God in every offering
अहं क्रतुरहं यज्ञः स्वधाहमहमौषधम्। मन्त्रोऽहमहमेवाज्यमहमग्निरहं हुतम् ॥
ahaṃ kraturahaṃ yajñaḥ svadhāhamahamauṣadham | mantro'hamahamevājyamahamagnirahaṃ hutam ||
Meaning
I am the ritual, I am the sacrifice, I am the offering to the ancestors, I am the healing herb. I am the mantra, I am the ghee, I am the fire and I am the act of offering.
