The sin that a Brahmana perpetrates in one night by respectfully serving a member of a lower caste or by playing with him in the same spot or on the same bed, is purified by observing the practice of sitting behind by observing the practice of sitting behind a Kshatriya or a Vaishya on a bed of dry grass for three years continually.
यदेकरात्रेण करोति पापं निकृष्टवर्णं ब्राह्मणः सेवमान:। स्थानासनाभ्यां विहरन् व्रती स त्रिभिर्वर्षेः शमयेदात्मपापम्॥
