Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 19

Sanskrit:

अथाह पौण्ड्रकं शौरिर्भो भो पौण्ड्रक यद् भवान् ।दूतवाक्येन मामाह तान्यस्‍त्रण्युत्सृजामि ते ॥ १९ ॥

ITRANS:

athāha pauṇḍrakaṁ śaurirbho bho pauṇḍraka yad bhavāndūta-vākyena mām āhatāny astraṇy utsṛjāmi te

Translation:

Lord Kṛṣṇa then addressed Pauṇḍraka: My dear Pauṇḍraka, the very weapons you spoke of through your messenger, I now release unto you.

Purport:

Śrīla Prabhupāda writes as follows in Kṛṣṇa: “At this time Lord Kṛṣṇa told Pauṇḍraka, ‘Pauṇḍraka, you requested Me to give up the symbols of Lord Viṣṇu, specifically My disc. Now I will give it up to you. Be careful! You falsely declare yourself to be Vāsudeva, imitating Me. Therefore no one is a greater fool than you.’ From this statement of Kṛṣṇa’s it is clear that any rascal who advertises himself as God is the greatest fool in human society.”
