Bhagavad Gita · 9.16

अहं क्रतुरहं यज्ञः स्वधाहमहमौषधम्।मन्त्रोऽहमहमेवाज्यमहमग्निरहं हुतम्॥

ahaṁ kratur ahaṁ yajñaḥ svadhāham aham auṣhadham mantro 'ham aham evājyam aham agnir ahaṁ hutam

I am the Vedic ritual, I am the sacrifice, I am the ancestral offering, I am the healing herb, I am the sacred chant, I am the clarified butter, I am the fire, and I am the act of offering.
