Bhagavad Gita · Raja Vidya Raja Guhya YogaChapter 9, Shloka 16 (9.16)

Shankaracharya. Ahaṃ kratuḥ śrauta-karma-bhedaḥ … ahaṃ yajñaḥ smārtaḥ — kratu = the Vedic (shrauta) rite, yajna = the rite of the smriti tradition; svadhā annam … pitṛbhyo yat dīyate — food offered to the ancestors; auṣadhaṃ sarva-prāṇibhiḥ yat adyate … vrīhi-yavādi-sādhāraṇam — the food of all beings (rice, barley and so on); an alternative: auṣadham iti vyādhy-upaśamanārthaṃ bheṣajam — medicine that relieves illness; mantraḥ … ājyaṃ haviś ca … agniḥ … hutaṃ havana-karma.

Acharya Ramanuja. ahaṃ kratuḥ ahaṃ jyotiṣṭomādika-kratuḥ aham eva yajñaḥ mahā-yajñaḥ — the kratu such as the Jyotishtoma, and the great yajna; svadhā pitṛ-gaṇa-puṣṭi-dāyinī — that which nourishes the ancestors; auṣadhaṃ haviḥ ca; pradarśanārtham idam — this is only an example; soma and all other oblations too are me.
