Meditate on the unknowable Self
तत्सर्वं भैरवं भाव्यं तदन्ते बोधसंभवः ||
Yadavedyam yadagrahyam yacchoonyam yadabhavagam|
Tatsarvam Bhairavam Bhavyam Tadanthe Bodhasambhavah||
All that which remains unknown and cannot be known, all that which can neither be held nor grasped, all that which remains as a void and all those unimaginable possibilities which have no existence - everything should be contemplated as Bhairava. At the end of such contemplation - true knowledge unfolds. - SS
