सत्कारमानपूजार्थं तपो दम्भेन चैव यत्। क्रियते तदिह प्रोक्तं राजसं चलमध्रुवम् ॥

satkāra-māna-pūjārthaṁ tapo dambhena chaiva yat kriyate tad iha proktaṁ rājasaṁ chalam adhruvam

The austerity which is practised with the object of gaining respect, honour and worship, and for ostentation, is said to be of passion, unstable and fleeting.

In plain words: Discipline done to win respect, praise or attention, or to show off, comes from passion. Its good effects do not last.
