अत्रैव सत्त्वात्मनि धीगुहाया -मव्याकृताकाश उरुप्रकाशः ।आकाश उच्चैरविवत्प्रकाशतेस्वतेजसा विश्वमिदं प्रकाशयन् ॥ १३४ ॥
In plain words
Right here, hidden in the quiet cave of the mind's own clarity, in that unmanifest inner space, an immense light is shining -- shining the way the sun blazes high in an open sky, lighting up this whole universe with a brilliance that is entirely its own.
Close to the Sanskrit
Right here, in the cave of the intellect whose nature is sattva, in the unmanifest space, one of vast splendor shines high in the sky like the sun, illumining this universe by his own light.
