“ ‘Being ordered by his father, Paraśurāma killed his mother, Reṇukā, just as if she were an enemy. When Lakṣmaṇa, the younger brother of Lord Rāmacandra, heard of this, He immediately engaged Himself in the service of His elder brother and accepted His orders. The order of the spiritual master must be obeyed without consideration.’
