Bhagavad-gītā As It Is · Text 17.5
Faith shaped by the three guṇas
अशास्त्रविहितं घोरं तप्यन्ते ये तपो जना: ।
दम्भाहङ्कारसंयुक्ता: कामरागबलान्विता: ॥ ५ ॥
कर्षयन्त: शरीरस्थं भूतग्राममचेतस: ।
मां चैवान्त: शरीरस्थं तान्विद्ध्यासुरनिश्चयान् ॥ ६ ॥
aśāstra-vihitaṁ ghoraṁ
tapyante ye tapo janāḥ
dambhāhaṅkāra-saṁyuktāḥ
kāma-rāga-balānvitāḥ
karṣayantaḥ śarīra-sthaṁ
bhūta-grāmam acetasaḥ
māṁ caivāntaḥ śarīra-sthaṁ
tān viddhy āsura-niścayān
Translation
Those who undergo severe austerities and penances not recommended in the scriptures, performing them out of pride and egoism, who are impelled by lust and attachment, who are foolish and who torture the material elements of the body as well as the Supersoul dwelling within, are to be known as demons.
