Bhagavad-Gita: Chapter 10, Verse 11

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

After bestowing the divine spark of spiritual intelligence the Supreme Lord Krishna residing within as paramatma the Supreme Soul makes sure it remains steady until His exclusive devotee eradicates all nescience and achieves atma tattva or realisation of their eternal soul and subsequent moksa or liberation from the material existence and samsara being the perpetual cycle of birth and death. This is what is meant by the words anukampa- artham which means He shows them special mercy out of great compassion for their devotion, the Supreme Lord blesses them and by His Grace all the darkness of material existence is illuminated. By what means is this accomplished and how is this done? Lord Krishna anticipating such a query speaks the words atma-bhava-stho meaning situated within their etheric heart as paratmatma, He illuminates their consciousness with the glowing radiance of spiritual knowledge.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

It is due to the loving compassion felt by the Supreme Lord Krishna for those persons who dedicate and devote their lives to Him that He is always manifest in their hearts and minds as the paramount object of their thoughts and plans and activities, accompanied by the realisation of His transcendental qualities and attributes. The words jnana-dipena meaning the radiant light of knowledge is verily Lord Krishna Himself in all their thoughts. Tamah or the darkness of ignorance to which beings are continuously subjected to is due to past and present karma or the reactions to one's actions. This tamah and karma are extremely antagonistic to spiritual intelligence and produce the desire for things material and temporary instead of things spiritual and eternal which lead to Lord Krishna; but for His devotees He dispels their tamah and dissolves their karma. Having comprehended the qualities, attributes and character of the Supreme Lord Krishna regarding His vibhuti or phenomenal, transcendental potencies manifesting throughout all of creation and His yoga or the science of the individual consciousness attaining communion with His ultimate consciousness, eternally. This knowledge will mature into appreciation which will evolve into bhakti or exclusive loving devotion for Him and subsequently unlimited bliss will naturally arise within the hearts and minds of His devotees.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Nevertheless in order to shower His grace exclusively upon those who worship Him in bhakti or exclusive loving devotion, He atma-bhava-stho meaning manifests within their hearts jnana-dipena the radiant knowledge of enlightenment which completely dispels all tamah or darkness of ignorance due to unlimited karma or multitudinous reactions from actions since time immemorial.
