Bhagavad-Gita: Chapter 10, Verse 39

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

Lord Krishna reveals that He is the bijam or root seed and germinating origin of all living entities because there is no living entity moving or stationary that can exist without Him.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

Lord Krishna is revealing that it is not possible for anything to exist without Him. The Moksa Dharma text reveals that the Supreme Lord who exhibited His universal form is of endless forms, of endless expansions, of endless manifestations, of endless incarnations and is verily the endless one.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

The bijam or root seed in all things and all beings which causes their appearance in whatever condition they may exist are all manifested by the Supreme Lord Krishna. Whatever the composite total of all beings in all of existence without Lord Krishna's manifestation as the atma or eternal soul within every living entity, there can be no possibility of existence in any manner of form. Lord Krishna exists in all things so this means that all things are always bonded to Him. It is evident from this that what is intended to be shown by samanadhi-karanya or co-existence of substance and attribute as one object is the reality of the Supreme Lord residing within all beings as the purely spiritual eternal soul. So it is apparent that all things have only their relative existences in relationship to the Supreme Lord.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Lord Krishna reveals that He is the bijam or root seed and origin of all beings existing in all situations and manifestations. There is nothing absolutely whatsoever animate or inanimate which can exist without Lord Krishna as He pervades the total material existence externally as the brahman or the spiritual substratum pervading all existence and internally as paramatma the Supreme Soul within the etheric heart of each and every living entity. From the primary creator Brahma above even the heavenly planets down to a blade of grass everything in existence is inseparably connected to Lord Krishna. As Lord Krishna is present within all causes He is naturally present in all results as well. He is the cause of all causes. The Svetavatara Upanisad VI.IX states: The Supreme Lord is the cause of the lord of all causes.
