Man should not do these things.

What are they ? 

In Hindu Sastras (ancient sacred scripts) say so many

Dharmas (Alms) for the mankind.  Among them, the man

should do certain things and should not do other things. 

Bad always must be eleminated from us. First if we know

 about the bad, naturally the good comes out of it. 

 What is the Light, when there is no darkness, every where there is light.

Here man mut not do these things under any circumstances. 

One  should not do Namaste (join palms as a mark of respect )

 to the running person, who is yawning and also 

who is taking  head bath.

One should not take the bath in the rivers, or sea when his

wife is pregnant. Like that he should not have the hair cutting

and also mountaineering.

One should not see the lady at the time of adorning her eyes . 

with collyrium (eye salve of black colour) (Anjanam in Sanskrit language)

and also when  the lady is bathing.

One should not watch the reflection ( pratibimbam) of the

Sun when it rises and setting time and also

should not see the Sun in the mirror.

One should not see his  own reflection in the water, should not

pluck the leaves of any tree at night and also at night one should not

 draw water from the well.

One should not have ejection of impurities and urinate 

at the time of applying oil on his head and the body.

One should not see his wife at the time when she is taking food,

 yawning and also sneezing. If it happens to see,

then better to see other side.

On every Chaturdasi day (fourteenth day of Sukla paksha and

 also Krishna paksha) (means twice in a month) one must

not drink the milk.

. And also he should sleep separately from

 his wife on the Amavasya Day.

One should not be without waist band (gridle)

(Kati Sutram in sanksrit language) at any time. 

So he should wear that gridle.

The woman  should not break the pumpking.

The man should not blown out the oil lamp.

 One must not admonish (reprimand) any animal which

drinks water and also the calf which drinks milk

from its mother. If it is done that  would be  a great  sin
