Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 31


यतो यतोऽसौ प्रहरत्परश्वधोमनोऽनिलौजा: परचक्रसूदन: ।ततस्ततश्छिन्नभुजोरुकन्धरानिपेतुरुर्व्यां हतसूतवाहना: ॥ ३१ ॥


yato yato ’sau praharat-paraśvadhomano-’nilaujāḥ para-cakra-sūdanaḥtatas tataś chinna-bhujoru-kandharānipetur urvyāṁ hata-sūta-vāhanāḥ


Lord Paraśurāma, being expert in killing the military strength of the enemy, worked with the speed of the mind and the wind, slicing his enemies with his chopper [paraśu]. Wherever he went, the enemies fell, their legs, arms and shoulders being severed, their chariot drivers killed, and their carriers, the elephants and horses, all annihilated.


In the beginning, when the army of the enemy was full of fighting soldiers, elephants and horses, Lord Paraśurāma proceeded into their midst at the speed of mind to kill them. When somewhat tired, he slowed down to the speed of wind and continued to kill the enemies vigorously. The speed of mind is greater than the speed of the wind.
