^Paths to The Divine: Ancient and Indian By George McLean, Vensus A. George, Quote: Siva: The Hermaphrodite The Lord Shiva is the underlying neutral and changeless reality, the undifferentiated absolute Consciousness, who is the foundation of every change and becoming. The hermaphrodite reality is one which is independent of all distinctions of male and female, the phenomenal and the non-phenomenal, and yet forms the basis of all such distinctions. The Puranas speak of Lord Shiva as the Hermaphrodite reality, though distinctionless within Himself, letting the distinctions of the manifold world spring up from Him. The Puranic thinkers interpreted and represented this hermaphrodite aspect of the Lord Siva in various ways. One such symbol expression is the figure of His Sakti. Another such symbol is the Phallus *(the male reproductive part) and the Yoni (the female reproductive part). A third, a more anthropomorphic metaphor, is that of the union between Siva and His many consorts, such as, Parvati, Uma and others. All these symbolisms express the truth that the variety of this universe stems from the lord Siva through his Sakti. To explain this point very picturesquely, the Puranas apply the mythological story of creation by way of the sexual union between Prajaapati and his daughter to Siva who, by His eternal union with His Sakti creates the world. The Puraanas also use another more sacrificial symbollism to expound the hermaphrodite characteristic of Shiva, according to which the male principle is represented as Fire, the devourer of the offering, and the female principle is the Soma, the devoured offering. In this symbolism, the hermaphrodite is the embodiment of the cosmic sacrifice, through which the universe emerges from the Lord Siva.
^Hijras of Muslim India and Pakistan etransgender.com; Quote: In North India and in Pakistan Hindus and Muslims alike believe in the powers of hijras to bless or curse others. To Hindus and Hindu hijras this is connected to the worship of Bahuchara Mata. Hindus believe that the powers of this feminine aspect of the divine flows in an almost shamanic way through the "eunuchs". In Pakistan and in traditional Indian Muslim families the mukhannath´ power to curse is called "bad du`a". This implies the faith that every supplicational prayer ("du`a") done by a faithful hijra will be fulfilled because she is specially blessed as a compensation for the fact that she is denied to have children and a "normal" family life as a born woman.
