Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 25

Sanskrit:

न विक्रिया विश्वसुहृत्सखस्यसाम्येन वीताभिमतेस्तवापि । महद्विमानात् स्वकृताद्धि माद‍ृङ्नङ्‌क्ष्यत्यदूरादपि शूलपाणि: ॥ २५ ॥

ITRANS:

na vikriyā viśva-suhṛt-sakhasyasāmyena vītābhimates tavāpimahad-vimānāt sva-kṛtād dhi mādṛṅnaṅkṣyaty adūrād api śūlapāṇiḥ

Translation:

O my dear lord, you are the friend of the Supreme Personality of Godhead, who is the friend of all living entities. You are therefore equal to everyone, and you are free from the bodily conception. Although I have committed an offense by insulting you, I know that there is no loss or gain for you due to my insult. You are fixed in your determination, but I have committed an offense. Because of this, even though I may be as strong as Lord Śiva, I shall be vanquished without delay due to my offense at the lotus feet of a Vaiṣṇava.

Purport:

Mahārāja Rahūgaṇa was very intelligent and conscious of the inauspicious effects arising from insulting a Vaiṣṇava. He was therefore very anxious to be excused by Jaḍa Bharata. Following in the footsteps of Mahārāja Rahūgaṇa, everyone should be very cautious not to commit an offense at the lotus feet of a Vaiṣṇava. Śrīla Vṛndāvana dāsa Ṭhākura in the Caitanya-bhāgavata (Madhya 13) says: “Even if one is as strong as Lord Śiva, who carries a trident in his hand, one will nonetheless fall down from his spiritual position if he tries to insult a Vaiṣṇava. That is the verdict of all Vedic scriptures.” He also says this in Caitanya-bhāgavata (Madhya 22): “One who blasphemes a Vaiṣṇava cannot be protected by anyone. Even if a person is as strong as Lord Śiva, if he blasphemes a Vaiṣṇava he is sure to be destroyed. This is the verdict of all śāstras. If one does not care for the verdict of the śāstras and dares blaspheme a Vaiṣṇava, he suffers life after life because of this.”
