Devavratha (Bhishma) took oath not to marry anyone in his life and also opted for lifelong celibacy so his father Shantanu could marry Satyavati who wanted her kids to rule Hastinapur. Criticism of King Shantanu from his subjects as to why he removed Bhishma from the title of the crown prince, as he was so capable, abounded. There was worry about the nobility of Shantanu’s unborn children, now promised the throne. Hearing this, Bhishma said it was his decision and his father should not be blamed as Shantanu had never promised anything to Satyavati’s father. The prime minister then asked who would be held responsible if the future crown prince isn’t capable enough. Bhishma then took another vow that he would always see his father’s image in whomever sat on the King’s throne, and would thus serve him faithfully.
