Vijnana Bhairava Tantra
126: The aspirant should maintain the attitude of neither aversion nor attachment toward anyone. Since he is freed of both aversion and attachment, there develops brahmabhava or the nature of the divine consciousness (which is also the nature of the essential Self) in his heart.
127: That which cannot be known, that which cannot be grasped, that which is elusive, that which is void, that which penetrates even non-existence, all that should be contemplated as Bhairava. At the end of that contemplation will occur Enlightenment.
128: Fixing the mind in the external space, which is eternal, without support, void, omnipresent and devoid of limitation, one enters into the formless, unmanifest dimension.
129: Towards whatever object the mind goes, one should remove it from there immediately by that very mind, and thus by not allowing it to settle down there i.e. by making is supportless, one will be free from agitation (of the mind).
130: The word Bhairava denotes he who dispels all fear and terror, who gives everything, and who pervades the entire universe (manifest and unmanifest). He who constantly repeats the word bhairava becomes one with Shiva.
