SB 9.16.8
uttasthus te kusalino
nidrapaya ivañjasa
pitur vidvams tapo-viryam
ramas cakre suhrd-vadham
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereafter, by the benediction of Jamadagni, Lord Parasurama’s mother and brothers immediately came alive and were very happy, as if awakened from sound sleep. Lord Parasurama had killed his relatives in accordance with his father’s order because he was fully aware of his father’s power, austerity and learning.
