KAṬHA UPANISHAD · 1.1.8

आशाप्रतीक्षे संगतँ सूनृतां
चेष्टापूर्ते पुत्रपशूँश्च सर्वान् ।
एतद्वृङ्क्ते पुरुषस्याल्पमेधसो
यस्यानश्नन्वसति ब्राह्मणो गृहे ॥ ८॥

āśāpratīkṣe saṃgatam̐ sūnṛtāṃ
ceṣṭāpūrte putrapaśūm̐śca sarvān ।
etadvṛṅkte puruṣasyālpamedhaso
yasyānaśnanvasati brāhmaṇo gṛhe ॥ 8॥

“That man of little understanding in whose house a Brahmin dwells fasting, all his hope and his expectation and all he has gained and the good and truth that he has spoken and the wells he has dug and the sacrifices he has offered and all his sons and his cattle are torn from him by that guest unhonoured.”

Sri Aurobindo · CWSA 18, p. 102
