Bhagavad-Gita: Chapter 9, Verse 17

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

Lord Krishna states that He is the dhata or bestower of the fruits of one's actions. He is vedyam or the essence of what is to be known and the sole object to be realised. He is pavitram the one who purifies and sanctifies. He is the His own personal sound vibration manifested in the sacred monosyllable OM and He is the sublime and perfect Rig Veda, Sama Veda and the Yajur Veda from where the Atharva Veda was extracted by Vedavayasa.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

The spiritual knowledge spoken previously is further narrated here. Rituals mean sacrifices of worship and propitiation. True sacrifice means the renunciation of wealth by humbly offering it in the service of the Supreme Lord. It is also stated in the Vedic sciptures that in relationship to the Supreme Lord the renunciation of wealth is considered sacrifice.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

It is the Supreme Lord Krishna who is the foundation and source of all creation comprised of moving and non-moving things hence His relationship as father, mother, grandsire and patriarch is natural. The word dhata meaning bequeather or dispenser denotes the original progenitor the Supreme Lord who is the real cause of all births distinct from the seminal birth from father and mother. He is vedyam whatever is perceptible by the Vedas being worthy to be known and He is the Holy sanctifier. He is the indicator known by His personal sound vibration OM which is the root of the Vedas and He Himself is the sacred Vedas comprised of the Rig, Sama and the Yajur Vedas from where was extracted the Atharva Veda.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Lord Krishna confirms that He is the sustainer of all creation and the actual impeller of all beings to create distinct from the seminal birth of parents. In this way He is the father, the mother and grandsire of all. He is the ultimate to be known and He the purifying sacred syllable OM His personal sound vibration and He is the sacred Rig, Sama and the Yajur Veda from where the Atharva Veda was extracted.
