तमोग्रस्तान पश्यंति प्रकाशंतमसावृताः । सुदुष्प्रकाश इत्याहुर्नरकं तम एव च ॥ ८३ ॥
tamograstāna paśyaṃti prakāśaṃtamasāvṛtāḥ | suduṣprakāśa ityāhurnarakaṃ tama eva ca || 83 ||
ผู้ถูกตมัสครอบงำย่อมเห็นแม้สิ่งที่สว่างไสวราวกับถูกความมืดปกคลุม. เขาเรียกว่า “สว่างได้ยากยิ่ง”; และตมัสนั้นเองคือสิ่งที่เป็นนรก.
Sanatkumara (teaching Narada in the Moksha-Dharma dialogue)
Vrata: none
Primary Rasa: bhayanaka
Secondary Rasa: shanta
It teaches that “hell” is not only a place but an inner condition: when tamas dominates, even clear truth appears obscure, and that obscuration itself becomes suffering.
By implying that devotion and remembrance of the Divine remove tamas; when the heart is purified, the “light” (dharma and truth) is naturally perceived rather than dismissed as unknowable.
No specific Vedanga is taught directly; the practical takeaway is discernment (viveka): recognize tamas-driven perceptions and counter them through disciplined study, ethical conduct, and steady spiritual practice.
