मूढग्राहेणात्मनो यत्पीडया क्रियते तपः | परस्योत्सादनार्थं वा तत्तामसमुदाहृतम्
mūḍhagrāheṇātmano yatpīḍayā kriyate tapaḥ . parasyotsādanārthaṃ vā tattāmasamudāhṛtam
那出於愚昧執著，以傷害自身，或為毀滅他人而實踐的苦行，被稱為答摩性 (Tamas) 之行。
That austerity which is undertaken with a foolish intent, by causing pain to oneself, or for the destruction of others-that is said to be born of tamas.
有些人將硫磺置於罐中燒灼並頂在頭上。有些人將鐵鉤刺入肉體。有些人頭下腳上懸掛於火上吞食煙霧。有些人浸泡於冰冷水中至頸部。有些人則在四方點火（以太陽為第五火，即「五火苦行」）。有些人坐於火圈中央。此類苦行皆屬答摩性 (Tamas)，無法助人證得真我。
Some burn sulphur in a pot and place it on their head. Some thrust hooks of iron into their flesh. Some hang themselves with their head downwards over fire and swallow smoke. Some stand in cold water immersed up to the neck. Some torture the body by lighting fires on the four sides (with the sun as the fifth fire -- this is known as the Panchagni Tapas). Some sit in the centre of a circle of fire. Such austerities are Tamasic. These will not help one to attain knowledge of the Self.
