मूढग्राहेणात्मनो यत् पीडया क्रियते तपः । परस्योत्सादनार्थं वा तत् तामसम् उदाहृतम् ॥

mūḍha-grāheṇātmano yat pīḍayā kriyate tapaḥ | parasyotsādanārthaṃ vā tat tāmasam udāhṛtam ||

Tāmasic tapas: done with foolish delusion, self-torture, or to destroy another — declared tāmasic.

Word by word (3)
mūḍha-grāheṇa ātmanaḥ yat pīḍayā kriyate tapaḥ
— tapas (tapaḥ) done (kriyate) by the seizure/grasp (grāheṇa) of delusion/foolishness (mūḍha), with self-torture (ātmanaḥ pīḍayā = torturing of the self) — mūḍha-grāha = the foolish conviction that self-torture itself is the path
parasyotsādanārtham vā
— or (vā) for the purpose (artham) of destroying/ruining (utsādana) another (parasya) — tapas as weapon against others; extreme asceticism used for cursing or destroying enemies
tat tāmasam udāhṛtam
— that (tat) is declared (udāhṛtam = said/stated) to be tāmasic (tāmasam) — the two-fold tāmasic corruption: self-destruction + other-destruction

That austerity which is practiced out of foolish conviction, with self-torture — or for the purpose of ruining/destroying another — that is declared tāmasic.

A modern analogy

Tāmasic tapas has two faces: one turns inward (mūḍha self-torture — harming oneself out of confused belief) and one turns outward (using accumulated tapas-power to destroy others). Both are rooted in tamas — delusion in the first case, malice in the second. Both are the opposite of the sāttvic V17 model where tapas serves genuine inner refinement.

V19 closes the three-fold tapas classification by defining tāmasic tapas through two pathological forms. The first (mūḍha-grāha + ātma-pīḍā) echoes V5-6: the āsurī who tortures their body out of dambha/ahaṃkāra — V19 calls this 'mūḍha-grāha' (foolish delusion), revealing that such tapas is ultimately tāmasic in quality. The second (parasyotsādanārtham) is the outward face: accumulated ascetic power directed against others. This second form is documented in the Purāṇas and Mahābhārata — tapas as weapon (cursing, burning, destroying) — here firmly classified as tāmasic.

The word mūḍha-grāha (foolish seizure/grasp) is important: 'grāha' means something that grabs and holds. It is the same root as 'grāhya' (to be grasped). The tāmasic person is in the grip of a delusion — they cannot release their false conception of tapas. This blindness (tamas = darkness = inability to see clearly) is what drives both self-harm and other-harm. Compare with V17's yukta (yoked, disciplined, with clear judgment) — the opposite of being seized by confusion.
