Bhagavad-Gita: Chapter 6, Verse 18

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

When does a person perfect the practise of yoga or the science of the individual consciousness attaining communion with the ultimate consciousness? The answer is when the mind becomes fixed and focused exclusively on the atma or soul within. Lord Krishna declares that at this time a person can be considered as having perfected yoga.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

The word atmany is used by Lord Krishna to indicate the eternal transcendental abode of the Supreme Lord.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

The words atmany evavatisthate means exclusively established in the atma or soul. This means the atma has become the highest goal and only object of endeavour. When the mind has been so tutored and regimented to be fixed and riveted to the atma so that it never strays away; it is simultaneously and automatically weaned from all desires for sense gratification having not the slightest interest to enjoy the objects of the senses. Lord Krishna is stating that at this time an aspirant is considered to possess the necessary qualifications to begin practising mediation.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

When will the persons qualified to practice yoga or the science of the individual consciousness attaining communion with then ultimate consciousness become established in yoga reaching perfection. Lord Krishna declares that when the mind refrains and abstains from all external mental activity and becomes exclusively riveted internally on the atma or soul within. Then it has been determined by experts that the mind is established in yoga.
