“In the Indian tradition,
stress would be the situation where a person
exhibits the Udvega, attitudes or behaviour
which take over a person and control him.
The origin of the Udvega lies in the Ṣad Ūrmi,
the six enemies.

These six are:
– Kāma: desire
– Krodha: anger
– Lobha: possessiveness, greed
– Moha: darkness;
though not actually dark it is as if darkness exists
because the person is so sure of himself
and his opinions that he is unable to see.
– Mada: arrogance,
the refusal to accept or give in.
– Mātsarya: jealousy,
to resent the success of others
and to be happy at their failures.

These are Āyurveda‘s Mano Roga.
If any one of these six is dominant in a person,
that person is sure to experience Udvega in one form or the other.”
