Verse 42

भावयन्नात्मनात्मानं चिद्रूपेणैव चिन्मयम् ।ऋजूज्ज्वलमये ह्यात्मा स्वयमात्मनि जृम्भते

In plain words

Contemplating the Self, which is consciousness through and through, by the Self in the form of consciousness alone, the Self of itself unfolds within itself, which is made of clear radiance.
