“In her most subtle, essential form, Yeshe Tsogyal is called ‘expanse of mahasukha Kuntusangmo [Samantabhadri], the all-good queen.’ This deity is called the primordial Mother Buddha, source of all enlightenment. She is the consort and female counterpart of Samantabhadra (Kuntusangpo), the primordial buddha of the Nyingma school, who represents the formless space of wisdom, the dharmakaya dimension of buddhahood in whom delusion and conceptual thought have never arisen. Samantabhadra is depicted as blue, the color of the sky, a reminder that his nature is limitless and formless as the sky. The feminine Samantabhadri is depicted as white and is the primary symbol of the awareness-wisdom aspect of the mind. Both are naked and unadorned, just as the mind and awareness always are in their essence. But it is Samantabhadri who is the expression of limitless space, the natural state that is ultimate truth.
Samantabhadri is the expression of that which cannot be expressed in words or symbols, the ultimate nature of mind, the limitless expanse of simplicity. This is the most subtle aspect of the dakini, beyond all dualities of gender, form, or expression. This aspect of the dakini must be experienced directly. All meditation practices in the Vajrayana tradition eventually point to this transformative experience. This is the secret power of the dakini, and it is to this that she points in all her manifestations.”
