Two methods have been told for this "taraka". The first is tangible and the other is intangible. Whatever in the mind is called tangible Taraka and the Taraka existing outside both brows is intangible. While discussing about the inner matters, one should do the exercise through concentration. By analysis regularly in one's heart (full of Satva merit), the luminating perfect Brahma in garb of true pleasure above the cornea of eyes is seen. It reveals that the Brahma is full of splendour and in white colour. That Brahma should be seen by intuition of the eyes. It makes able to know that the Brahma is full of splendour and white colour. The intangible Taraka too, is known through the same process of the mind's eyes. The mind is dependent to the eyes in the matter of seeing the complexion. Analogous to the external, the internal cognisance of the complexion is also made by these two. This is the reason; the light of Taraka becomes by the eyes including the mind.
