The dot symbolizes the target acquired by most Muslim and Sikh lovers of the hindu "faith".
Cows see this dot as a convenient place to urinate, so it can dribble down the face of the hindu worshipper, and right into his mouth.
Cow urine is a common drink among hindu followers, and they will also feast on cow feces on some occasions.
Hindus fear the wrath of the cow, so they buy cows gifts often, and the cows just end up taking massive dumps on these gifts.
Hindus also have a big affinity to monkeys and elephants, because they too, are hindu Gods.
A hindu man's attainment of Nirvana is complete when he has anally pleasured an elephant and a baby monkey on the same day. He will then go home and ejaculate all over his daughter's face while she consumes the semen thinking it is holy.
