यथा दीपो निवातस्थो नेङ्गते सोपमा स्मृता।
योगिनो यतचित्तस्य युञ्जतो योगमात्मनः।।6.19।।
।।6.19।।जैसे स्पन्दनरहित वायुके स्थानमें स्थित दीपककी लौ चेष्टारहित हो जाती है योगका अभ्यास करते हुए यतचित्तवाले योगीके चित्तकी वैसी ही उपमा कही गयी है।
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.
