lion’s roar ［師子吼・獅子吼］ ( simhanāda;  shishi-ku): Also, roar of a lion. The voice or preaching of a Buddha. A Buddha’s preaching is likened to the roar of a lion, because a Buddha preaches the Law without fear, refutes erroneous doctrines, and fills persons who uphold erroneous doctrines with awe. The Sanskrit term simhanāda is a compound of simha (lion) and nāda (roar).
