Enumeration of the Properties of the Elements and Cognitive Faculties
जो दुष्कर्मपरायण और अशुद्ध अन्तःकरणवाले हैं, वे अज्ञानी पुरुष अन्यायपूर्वक मनोवाञ्छित विषयोंमें विचरनेवाली इन्ट्रियोंद्वारा आत्माका दर्शन नहीं कर सकते ।।
ye duṣkarmaparāyaṇā aśuddhāntaḥkaraṇā ajñāninaḥ puruṣā anyāyapūrvakaṃ manovāñchitaviṣayeṣu vicarantībhir indriyaiḥ ātmadarśanaṃ na śaknuvanti | teṣāṃ tu manasā raśmīn yadā samyak niyacchati | tadā prakāśate 'syātmā dīpadīptā yathākṛtiḥ ||
悪業に傾き、内なる器官が不浄で、真の分別を欠く者は、欲する対象の間を不正にさまよう感官によって真我を観ることはできない。だが人が心（マナス）によって感官という馬の手綱を堅く引き、正しく制御するなら、そのとき真我は智慧の光のうちに顕現する—灯火の照らしによって物の形が明瞭に見えるように。

Educational Q&A
Self-realization is blocked by immoral conduct and inner impurity; when the mind restrains the senses like reins controlling horses, the Self becomes clearly manifest, as an object is seen by lamplight.
Vyāsa is instructing on the conditions for perceiving the Ātman: he contrasts the unrestrained, desire-driven life that cannot yield inner vision with disciplined control of the senses that reveals the Self through the light of knowledge.
