“Udakamu travedu hayamunu
Madamuna nupponguchundu mattebhambun
Modavukadanunna vrushabham
Jaduvani aneechu kadaku janakura Sumathi”
This can be translated as
“one should not go near
A horse drinking water
A young wild elephant
A bull mating with a cow
An uncouth illiterate plebeian / reprobate”
This poem basically elucidates the situations which should be avoided. If one approaches a Horse which is drinking water, that person will be approaching from behind. The horse may fear that it is getting disturbed and strikes with its hind legs. A young wild elephant will be moving without any rhyme and reason and control. It is fatal to go near such an elephant. Similarly a bull in heat mating with a cow will turn wild if interrupted.
In the same way an illiterate, uncouth plebeian does not know how to behave and talk. He may behave in such a way which may be insulting to a normal person. It is advised to avoid such a person as far as possible.
