Mbh 13.104.2c

One should dress one's hair, apply collyrium to one's eyes, and wash one's teeth, as also worship the deities, in the forenoon. One should not gaze at urine or faeces, or tread on it or touch it with one's feet. One should not set 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 Sudra, or alone. While going along a road, one should, standing aside, always make way to a Brahmana, to kine, to kings, to an old man, to one that is weighted with a burden, to a woman quick 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 a spot where four roads meet, walk round it before pursuing one's journey. At midday, or at midnight, or at night in general, or at the two twilights, one should not proceed to spots where four roads meet. One should never wear sandals or clothes that have been worn by another. One should always observe the vow of Brahmacharya, and should never cross one's legs. One should observe the vow of Brahmacharya on the day of the new moon, as also on that of the full moon, as also on the eighth lunar day of both fortnights. One should never eat the flesh of animals not slain in sacrifice. One should never eat the flesh of the back of an animal. One should avoid censuring and calumniating others, as also all kinds of deceitful behaviour.[461] One should never pierce others with wordy shafts. Indeed, one should never utter any cruel speech. One should never accept a gift from a person that is low and vulgar. One should never utter such words as trouble other people or as are inauspicious or are as sinful. Wordy shafts fall from the mouth. Pierced therewith, the victim grieves day and night. The man of wisdom should never shoot them for piercing the vitals of other people. A forest, pierced with shafts or cut down with the axe, grows again.
