He will have a son of the name of Richika. The whole science of arms, O sinless one, on its embodied form, will come to him, for the extermination of the entire Kshatriya caste, through a decree of Destiny. Receiving that science by inward light, he will, by Yogapower, communicate it to his son, the highly blessed Jamadagni of purified soul. That foremost of Bhrigu's race will bear that science in his mind.
