Из комментария Мунидатты (Munidatta) к «Чарьягитикоше» (Caryagitikosa) Вирупы:

The unique Central Channel brings together the two subsidiary channels of the right and left above at the nose, to produce firmness of self-consecration. Below they are also fused at the genital organ to bind the relative thought of awakening and to produce the highest bliss.
The absolute thought of awakening is made firm through binding the relative thought of awakening with the noose of the coemergent bliss.
