Shukra, the word mentioned earlier means 'white' or 'bright' in Sanskrit. And then, an interesting myth about Shukra:
In Vedic myth the Asuras are the demonic aspect of the divine and, like many of the ancient creation myths, are locked in eternal battle with the Devas, the auspicious aspect of the Divine. In one episodic myth the Devas are particularly concerned in their battle with Asuras because Venus knows the mantra of immortality to raise the dead. This of course gave the Asuras an unfair advantage in their battle with the Devas. So Jupiter, or Brihaspati, the guru to the Devas, sends his son Kaca (brightness) to study under Sukra, ather of the Vedic Venus, Devayani..
Sukra has a beautiful daughter Devayani, and she is quite taken with Kaca. Now, the Asuras know what Kaca is up to, so like all good demons they kill him. Devayani, of course, grieves for him and tells father, so Sukra repeats the mantra and Kaca comes back to life. Then the demons kill Kaca again.
Once again Devayani complains, and once again Sukra repeats the mantra and Kaca come back to life. Undeterred, the demons go about killing Kaca and Sukra keeps resurrecting him. So the demons get a particularly demonic idea and this time they kill Kaca and grind him up into a fine powder and put him in Sukra's wine. Sukra drinks the wine, Devayani begins her grieving, and in response Sukra repeats the mantra, but this time he has a stomachache as Kaca speaks from inside him. At last the demons appear to be happy.
But, they ironically bring about the very thing they were trying to prevent, for Sukra reveals the mantra of immortality to Kaca, so when Kaca tears himself out of Sukra's body he will repeat the mantra and raise Sukra from the dead. This myth explains why all Brahmins committed to spiritual life are not allowed to drink wine, and one of the epithets of Venus is: the one who "produces stomach problems".
Sukra bestows long life, wealth, happiness, children, and property and good education. He is the Guru for Asuras. Well learned in Neeti Sastras follower of such sastras and one who dispenses justice, Sukra is considered a beneficial Devata. He blesses the devotees with power to control one's Indriyas (Sense organs) and enables the devotee to obtain fame and name.
In the Zodiac, he is the Lord of Tula (Libra). Sukra takes one year to complete the Zodiac cycle living one month in each Rasi. Fridays are considered to be effective for the worship of Sukra.http://www.crystalinks.com/venusmyth.html
Kaca (Brightness) refers to sun. In the story the sun dies and rises again. This is a reference to day and night.
Simply told, The son of the priest of Gods is sent to study under the priest of Demons, he falls in love with the daughter of the priest of Demons, and comes to know the mantra for immortality.
