When joke is implied with reference to an action, the verb denoting it is used in the 2nd person; provided that the word manya 'to think' is the attendant word (upapada) of such verb and of the verb manya itself, the affix must be of the 1st person and singular number.,
The word प्रहास means joke, sport. As एवं मन्ये ओदनं भोक्ष्यसे इति; नहि भोक्ष्यसे, भुक्तः सोऽतिथिमिः. Thus thou thinkest 'I shall eat rice,' thou shalt not eat, that has been eaten by a guest. एहि मन्ये रथेन यास्यसि नहि यास्यसि, यातस्तेन ते पिता. I think thou wilt go by the chariot, no, thou wilt not, thy father has gone before thee on it. When joke is not intended, the proper persons should be used: as, एहि मन्यसे ओदनं भोक्ष्ये. Thus thou thinkest 'I shall eat rice.',
