आलस्यात्मूर्खसंयोगाद्भयाद्रोगनिपीडनात् ।
अत्यशक्त्याच्च मानाच्च षड्भिर्विद्या विनश्यति ॥
ālasyāt mūrkha-saṁyogād bhayād roga-nipīḍanāt |
atyaśaktyāc ca mānāc ca ṣaḍbhir vidyā vinaśyati ||
(Māṇḍūkī-śikṣā: 180)
“Because of laziness, because of companionship with fools, because of fear, because of the pain of a disease, because of severe inability, and because of conceit—learning is ruined by these six.”
