Ramayana
तृप्तिर्न ते ऽस्ति सूक्ष्मा ऽपि वने सत्वनिषेविते । पुरा तु भिक्षमाणाय भिक्षा वै यतये नृप । न हि दत्ता त्वयेन्द्राभ यस्मादतिथये ऽपि वै ॥ 7-78-16 ॥
There is not even the slightest satisfaction for you in this forest haunted by wild beasts. For in former times, O king, when an ascetic came to you begging for alms, you gave him nothing; and because of that, O Indra-like one, you gave nothing even to a guest.
