Medhātithi’s commentary (manubhāṣya):
‘Exertion without a purpose’—i.e., that which does not bring any benefit, preceptible or imperceptible; e.g., hankering after news of other countries, and so forth.

‘Añjali’ is joined palms;—with this ‘he shall not drink water.’ Since water is mentioned by name, the prohibition does not apply to milk and other liquids.

‘Articles of food in his lap’—fried grains and cakes, &c., he shall not eat, while they are on his thighs. The term ‘articles of food’ extends the prohibition to fruits also. As for rice, the mixture of fried Hour with water and such other semi-liquid things as cannot be eaten without mixing water,—there is no possibility of their being eaten on the lap.

‘Curiosity’—is over-eagerness for information about things, without any purpose.

‘Na jātu’—never.—(63).
