CHĀNDOGYA UPANISHAD · 4.16.3

अन्यतराम् एव वर्तनीं संस्करोति ।
हीयते ऽन्यतरा ।
स यथैकपाद् व्रजन् रथो वैकेन चक्रेण वर्तमानो रिष्यत्य् एवम् अस्य यज्ञो रिष्यति ।
यज्ञं रिष्यन्तं यजमानो ऽनु रिष्यति ।
स इष्ट्वा पापीयान् भवति ॥

anyatarām eva vartanīṃ saṃskaroti ।
hīyate ’nyatarā ।
sa yathaikapād vrajan ratho vaikena cakreṇa vartamāno riṣyaty evam asya yajño riṣyati ।
yajñaṃ riṣyantaṃ yajamāno ’nu riṣyati ।
sa iṣṭvā pāpīyān bhavati ॥

He performs perfectly the one way only (that by words), but the other is injured. As a man walking on one foot, or a carriage going on one wheel, is injured, his sacrifice is injured, and with the injured sacrifice the sacrificer is injured; yes, having sacrificed, he becomes worse.
