The aspirated 'HA' is symbolized by Discriminating Wisdom by the Dhyana Buddha, Amitibha. The lust or greed, the aggregate of feelings or attachment, the ghost world and the color red are the samsaric manifestations transmuted to become the Discriminating Wisdom which is the confered siddhi (extraordinary ability) of knowing each thing by itself and all things as One. Discriminating Wisdom manifests itself through the element fire, which produces the vital heat of embodied human and lower animal beings.
