Bhagavad Gita 16.23
यः शास्त्रविधिमुत्सृज्य वर्तते कामकारतः।न स सिद्धिमवाप्नोति न सुखं न परां गतिम्॥
yaḥ śāstravidhimutsṛjya vartate kāmakārataḥ |na sa siddhimavāpnoti na sukhaṃ na parāṃ gatim ||
He who, having cast aside the ordinances of the scriptures, acts under the impulse of desire, does not attain perfection, nor happiness, nor the Supreme Goal.
But he who neglects the commands of the scriptures and follows the promptings of passion does not attain perfection, happiness, or the final goal.
