Jamadagni was certainly very powerful due to his austerities, but because of a slight offense by his poor wife, ReṇukÄ, he ordered that she be killed. This certainly was a sinful act, and therefore Jamadagni was killed by the sons of KÄrtavÄ«ryÄrjuna, as described herein. Lord ParaÅ›urÄma was also infected by sin because of killing KÄrtavÄ«ryÄrjuna, although this was not very offensive. Therefore, whether one be KÄrtavÄ«ryÄrjuna, Lord ParaÅ›urÄma, Jamadagni or whoever one may be, one must act very cautiously and sagaciously; otherwise one must suffer the results of sinful activities. This is the lesson we receive from Vedic literature.
