Bhagavad Gita 16.22

एतैर्विमुक्तः कौन्तेय तमोद्वारैस्त्रिभिर्नरः।आचरत्यात्मनः श्रेयस्ततो याति परां गतिम्॥

etairvimuktaḥ kaunteya tamodvāraistribhirnaraḥ |ācaratyātmanaḥ śreyastato yāti parāṃ gatim ||

A person who is liberated from these three gates of darkness, O Arjuna, practices what is beneficial for them and thus goes to the Supreme Goal.

These are the gates that lead to darkness; if one avoids them, they will ensure their own welfare and eventually attain liberation.

Our plain-language meaning of this verse is waiting for scholar review.
