Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear sir, I am not at all afraid of the thunderbolt of King Indra, nor am I afraid of the serpentine, piercing trident of Lord Siva. I do not care about the punishment of Yamaraja, the superintendent of death, nor am I afraid of fire, scorching sun, moon, wind, nor the weapons of Kuvera. Yet I am afraid of offending a brahmana. I am very much afraid of this.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When Sri Caitanya Mahaprabhu was instructing Rupa Gosvami at the Dasasvamedha-ghata in Prayaga, He pointed out very clearly the seriousness of offending a Vaisnava. He compared the vaisnava-aparadha to hati mata, a mad elephant. When a mad elephant enters a garden, it spoils all the fruits and flowers. Similarly, if one offends a Vaisnava, he spoils all his spiritual assets. Offending a brahmana is very dangerous, and this was known to Maharaja Rahugana. He therefore frankly admitted his fault. There are many dangerous things — thunderbolts, fire, Yamaraja’s punishment, the punishment of Lord Siva’s trident, and so forth — but none is considered as serious as offending a brahmana like Jada Bharata. Therefore Maharaja Rahugana immediately descended from his palanquin and fell flat before the lotus feet of the brahmana Jada Bharata just to be excused.
