The story of siddha Chaurangi [dismembered stepson]
Chaurangi's father took another young princess as his queen after the death of his queen mother. A few days later, when the king went for a walk in the forest to relieve his grief, the young queen Chitrangi saw Chaurangi from the top of her mansion and developed a passion for him. She sent a messenger to ask him to visit her, but Chaurangi refused. Chitrangi's feelings were hurt and she was determined to kill him at any cost.
Chitrangi staged a scene of being molested and raped. She scratched all over her body, and there was blood on her body. She was sitting on her bed with no clothes on. When the king saw this, he asked her what had happened. She told him it was done by his son, Chaurangi. The King was enraged and said that for such an action the prince should be killed. He assigned two butchers and ordered them to take him to the forest and amputate his arms and legs. So the butchers chopped his arms and legs, and left him there.
At that time, Minapa (Minanatha) was in the area. Minapa saw a cowherd (Gorakhnath) and asked him to go to the place where the vultures are circling. He said he would find an amputated man under a tree. Gorakhnath went there, gave him food and took care of Chaurangi for twelve years. One day, Gorakhnath saw Chaurangi standing up! Chaurangi's limbs has grown back. Gorakha the cowherd went back to his place and continued tending his cattle. Mahasiddha Minapa came to see Gorakhnath. Minapa gave teachings and empowerment to Gorakhnath. Gorakhnath practised those teachings and attained the siddhis of Mahamudra.
Doha of Gorakṣanātha from Tibetan Tengyur text
(They) are from the highest, middling, and lowest caste (respectively). By the potent karma and the favourable circumstance, Marvellous is the fruit of the unstoppable power of Karma! Served and venerated Mahasiddha Caurangi with affection, Thereby arises the seed of elements. Macinda (Maccindra) established the nectar of immortality, Thereby Goraksha saw the nonduality. How marvellous is the cowherd (Goraksha), the king of the three worlds!
Doha of Mahasiddha Chaurangi from Tibetan Tengyur text
For eons and eons, beginningless Samsara, To the roots of the tree of ignorance, Well watered by the Samskara, Has grown and flourished numerous branches of Samsara. But now, Chorangi cuts that giant tree of ignorance, By the sacred teachings of (his) Gurus, With the axe of three Prajnas!
