He shall never approach a place difficult of access, which is not within range of his vision; he shall not look at urine or excreta; nor shall he cross a river with his arms—(77)

Medhātithi’s commentary (manubhāṣya):
‘Difficult of access.’— Mountains and such places as can be got at with difficulty; as also a forest dense with trees, shrubs and creepers.

‘He shall not approach.’—He shall not pass over, shall not go to.

‘Which is not within the range of his vision;’—because there is danger of snakes and robbers, etc., lying hidden there. The ‘Eye’ includes also the other sources of knowledge, such as the Scriptures, for Instance.

‘Urine and excreta’—‘Looking at’—these mean examining their colour, etc. This extends over a long time; and hence should not be done. There is no harm in seeing it once by the way.

Swimming a river is forbidden for a man in the normal state; and not when there is danger apprehended from wolves and other animals.—(77)

The last foot of this verse is quoted in Aparārka (p. 183).
