One should not gaze at urine or faeces, or tread on it or touch it with one's feet. One should not see out on a journey at early dawn, or at midday, or in the evening twilight, or with a companion that is unknown, or with a Shudra, or alone. While passing along a road, one should standing aside, always give way to a Brahmana, to kine, to kings, to an old man, to one that is loaded with a burthen, to a woman big with child, or to one that is weak. When one meets a large tree that is known, one should walk round it. One should also, when coming upon the crossing of four roads, walk round it before pursuing his journey. At midday, or at midnight, or at night in general, or at the two twilight's, one should not proceed the crossings of the four roads. One should never wear sandals or clothes that have been worn by another.
