Shiva Purana
गंगातोयेन सर्वेण मृद्भारैः पर्वतोपमैः ॥ आमृत्योराचरेच्छौचं भावदुष्टो न शुध्यति ॥ १८ ॥
But let him be cleaned with all the waters of the Gaṅgā, with heaps of sand resembling a mountain or let him observe purificatory rites till death, if a man has wicked feelings and emotions he can never be purified.
