That firmness, O Arjuna, by which a stupid man does not abandon sleep, fear, grief, despair, and conceit, is Tamasic.

Swami Sivananda

That firmness is considered to be born of tamas, due to which a person with a corrupt intellect does not give up sleep, fear, sorrow, despondency, as well as sensuality.

Swami Gambirananda

Follows the commentary of Shankara (Advaita).

That Dhrti, by which a foolish person does not give up sleep, fear, grief, depression, and passion, O Arjuna, is of the nature of Tamas.

Swami Adidevananda

Follows the commentary of Ramanuja (Vishishtadvaita).

The contentment where a foolish man does not give up his sleep, fear, grief, despondency, and arrogance—that contentment is deemed to be of the Tamas (Strand).

Dr. S. Sankaranarayan

Follows the commentary of Abhinavagupta (Kashmir Shaivism).

And that which clings perversely to false idealism, fear, grief, despair, and vanity is the product of ignorance.

Shri Purohit Swami

हे पार्थ ! दुष्ट बुद्धिवाला मनुष्य जिस धृतिके द्वारा निद्रा, भय, चिन्ता, दुःख और घमण्डको भी नहीं छोड़ता, वह धृति तामसी है।

Swami Ramsukhdas

हो पार्थ ! दुर्बुद्धि पुरुष जिस धारणा के द्वारा, स्वप्न, भय, शोक, विषाद और मद को नहीं त्यागता है, वह धृति तामसी है।
