visoka va jyotisman sutra delineates that a sadhaka can maintain inner stability and consciousness through the rigorous process of preserving stillness and quietening the citta. This can bring about a liberated state of the heart, a reflecting, radiant, and beamy stage, where the core shines like an ocean.

visoka free from grief, sorrowless effulgent light
va or
jyotismatl luminous, bright, shining, possessed of luminous bodies, a tranquil state of mind

Or, inner stability can also be gained by contemplating a luminous, sorrowless, effulgent light.

Here, the concentration is on the innermost nucleus of the heart, where alone the sorrowless, effulgent light luminescences. That is the seat of the soul. The mind is guided in such a way that it becomes absorbed, and imbues towards its source. Movements in the form of thoughts in the mind are the waves, and citta, or the seat of consciousness, is the ocean. The sadhaka must learn to keep the citta motionless and thoughtfully silent, without creating waves of thought. This effort of stilling and silencing the citta brings forth the sorrow less effulgent light of the soul.
