Bhagavad-Gita: Chapter 6, Verse 19

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

A simile is given in this verse by Lord Krishna in His comparison of a candle flame that never wavers in a windless place and the mind of a yogi or one perfected in the science of the individual consciousness attaining communion with the ultimate consciousness, rapt in concentrated meditation, bright and steady like a flame never flickering away from the atma or soul.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

Here Lord Krishna uses the word atmanah to indicate the eternal, resplendent Supreme Lord Himself.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

As a candle flame when sheltered from the wind will not flicker but burns bright and steady. The word smrta means evidenced and is cited by those who are experienced in the science of meditation and used as a simile to illustrate how meditation on the atma or soul becomes steady and effulgent to that yogi or one perfected in the science of the individual consciousness attaining communion with the ultimate consciousness who concentrates upon the atma after with drawing the mind from every other objects of attention. Lord Krishna is stating that the atma shines steady and radiant in the light of meditative spiritual intelligence by reason that all extraneous and miscellaneous distractions of the mind have been sequestered out exactly as a candle flame shines constant and bright when all wind has been sequestered out from around it.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

In this manner Lord Krishna describes the characteristics of one established in yoga or the science of the individual consciousness attaining communion with the ultimate consciousness. Now He gives a simile comparing an unwavering flame in a windless place with the mind of a yogi rapt in concentrated mediatation on the atma or soul. The purport is as a candle flame is sheltered from the wind, the mind of a yogi shines bright by the unflickering effulgence of the atma.
