हितोपदेश - मित्रलाभ - अतिथि

बालो वा यदि वा वृद्धो युवा वा गृहमागतः ।
तस्य पूजा विधातव्या सर्वत्राभ्यागतो गुरुः ॥

- हितोपदेश, मित्रलाभ

One must treat a guest with lot o respect and affection irrespective of whether he is a child, or youth or an old person. A guest in the house should be treated with the same respect as a teacher.
