एकाक्षरप्रदातारं यो गुरुं नाभिवन्दते ।
श्वानयोनिशतं गत्वा चाण्डालेष्वभिजायते ॥
ekākṣara-pradātāraṁ yo guruṁ nābhivandate |
śvāna-yoni-śataṁ gatvā cāṇḍāleṣv abhijāyate ||
(Cāṇakya-nīti-darpaṇa: 13.20)
“One who does not respect a guru who has taught [even] a single syllable will undergo one hundred births as a dog and then be born among cāṇḍālas.”
