As
Surya is partially malefic (
Krura Graha) by its nature, thus
Sunday generally is considered to be a day for either for
Paapa (sinful, unethical, cruel actions) or some
Shubha (auspicious)
Karmas
only if certain benefic work isn't specified for it. Its nature is
"fixed & stationary" (in ancient
Sanskrit - "
Dhruva" or
"Sthira"), thus all "fixed & stationary" works are
good on
Sunday. In combination with "fixed & stationary"
Nakshatras (
Rohini,
Uttara Phalguni,
Uttara Bhadrapada,
Uttara Ashada) activity related to this
Nakshatras will be very fruitful. As for effectiveness -
Sunday
is effective during day-time. This day is auspiscious for everything
related to copper-red, blood red, sunrise colour, government, father,
king, ego, self-esteem, truth,
Sattva, cleariness, health etc (as
Surya,
a ruler of this day, rules all these things). All works that somehow
are related to destroying something on the way to light or getting
health are very auspicious (as
Shiva, who's responsible for destroying all obstacles on the way to
Moksha is a tutelary
Devata of
Sunday. It's very auspicious to appeal to
Shiva while trying to do something important during
Sunday).
Adhi-Devata of
Sunday is
Agni, who's very similar to
Surya by its nature. Thus,
Sunday is a very auspiscious day for anything that's related to
Agni, fire, light and all similar things.
Basing on mentioned parameters works in following fields are especially prescribed for Sunday: coronation, service to government / king, worshipping of king, service & employment; works related to fire,
weapon making & usage, war, bravery, travel, thief catching;
doctor, transaction of medicine; purchase of cows, bullocks &
