According to the curators of the Himalayan Art Resources,[10] the wisdom Dakini Simhamukha is visualized with a body blue-black in colour, one face, two hands; three eyes, red, round and glaring; bared fangs and a curled tongue.
Orange hair, eyebrows and beard flowing upwards, with five dry human heads as a crown and fifty wet, blood dripping, as a necklace.
With five bone ornaments and a tiger skin as a lower garment; standing on the left leg with the right drawn-up, in the middle of a blazing fire of pristine awareness.
[13] According to Jamyang Khyentse Wangpo, The uncommon lineage of the inner and secret empowerments and activity liturgies of the white, black and varied, is: Dharmakāya Samantabhadra in union, The wisdom ḍākinī Simḥamukhā, The unequalled Guru of Uḍḍiyāna in union, The realized Namkha Sangye Gönpo, The destroyer of illusion, the great Repa Kunga Darpo, The Mantra-holder Tsöndru Senge, From whom my root teacher Chökyi Nyima received the teachings on Siṃhamukhā.
[14] The Sakya lineage began with a terma discovered by Bari Lotsawa (1040–1111), who transmitted the teachings to Sachen Kunga Nyingpo.
