Above is a link to a ancient story of a flood called the flood story of Atrahasis. There are a number of old flood stories. One of them is in the bible and involves Noah and his ark. Another one is in vedic literature. And there is a flood story in the story of Gilgamesh which is an old sumerian myth. The ancient world has many flood stories.
In the flood story of Atrahasis there is a flood that engulfs the whole world. Atrahasis survives on an ark and after he returns to land he is given instructions on what to do. The flood occurred because the gods felt there was too many people on the planet and the gods claimed that people were being too noisy and thus bothering the gods. The instructions the gods gave to Atrahasis after he returned to land were to establish monastic orders where some of the population was celibate in an effort to combat the potential of overopulation.
As far as the issue of overpopulation goes I do not advocate that people be hurt in order to combat overpopulation. I am against abortion. However people voluntarily being celibate is something which I am not opposed to.
Celibacy is not for everyone though. Some people prefer chastity to celibacy. The difference between chastity and celibacy is that chaste people avoid masturbation yet they have sex in order to make babies. A celibate person avoids all sexual activity. If a person avoids sex but does engage in masturbation they are not being celibate, in that case they are a wanker.
A quote from the link regarding monastic celibacy
etablish high priestesses and priestesses,
let them be taboo [celibate], and so cut down childbirth.
Those who are breeders should aim to be chaste. By conserving the sexual energy one should aim to transmute the sexual energy into spiritual sentiment. Both the celibate and the chaste breeder should work to transmute the sexual energy.
The Zoroastrian faith has a flood myth as well. Above is a Zoroastrian prayer/mantra/proverb. According to Zoroastrianism one should work to think good thoughts, say good words, and do good deeds. In order to think good thoughts, say good words, and do good deeds one must be in touch with ones conscience and to be in touch with ones conscience one should be in a constant state of prayer because it is by praying that one is reminded of God and by being reminded of God one is reminded of sin and by being reminded of sin one is reminded of ones conscience.
The ancient Zoroastrians were a vegetarian people.
Below is a link to a website devoted to Zoroastrian revival.
Some people claim that celibacy is unnatural and that all humans should reproduce. Well let us take a look at nature then. Among wolf packs in the wild there are only a few wolves in a pack who are breeders. The other wolves in the pack do not breed.
It is not being implied which is better: chastity or celibacy. One will have to find for oneself whether one is a breeder or not. But one must think on this carefully.
