Concentrate on space as omnipresent free of all limitations. Withdraw attention from distracting object and concentrate on the object of meditation. Recite the name Bhairava incessantly. Think of the sense of words which are eternal, omnipresent, have no support, pervade and is the Lord of all that is. The whole universe has the reality of a magic show.
All external objects are based on knowledge, therefore the world is void.
There is no bondage or liberation, the universe is a reflection like the Sun in water. All contact with pleasure and pain is through the senses. If you detach the senses from oneself, you can withdraw. Concentrate on the Knower and the Known as one and the same.
