Sexual union, pregnancy and reproduction of human species are the essentials on which the world exists. Sexual union should never be based upon simple sense gratification.

The time of conception (Garbhadhaana) is very important and should be carefully planned.

The value of time is inestimable. All objects in nature are produced in Time, developed in Time and destroyed in Time.

The truth of these statements requires no further proof. It stands unchallenged.Time has got it's own properties. Creative, protective and destructive forces are embedded in the womb of time. If there could be a tool, which can give us a clue as to when the various kinds of creative and destructive forces are in operation, it would be of great help. A person can time his efforts to do the right thing at the right moment so that his activities are in harmony with the laws of nature.

To understand it further, just see that there is a time to sow and a time to reap. Why not we do the sowing operation during the harvest season? Nature would be against us. During the sowing season, creative forces are in operation. When an important activity is to be undertaken, destructive forces have to be screened off. Thus, the time of conception (Garbhadhaana) is very important.

The birth of Ved Vyaas, the great scholar and the author of Mahabharata is believed to have been the culmination of a union at a time when planetary positions were conductive to produce a philosopher. Each moment has got its own potency. The moment at which we elect to do an important act is not certainly an insignificant epoch.

Maharishies have given us clues as to how best we can make use of the grand constructive vibrations operating in nature if our endeavors are to be endowed with success.

For those who are not much adept in astrology, the simple formulae for the birth of a dutiful, intelligent and virtuous child, a couple should try for conception (Garbhadhaana) keeping in mind that:

a. The constellations (Nakshatras) Shravana, Rohini, Anuradha, Swati, Revati, Moola, Uttarashada, Uttarabhadrapad, Shatbhisha are highly favourable for nuptials.

b. The constellations Pushya, Dhanishta, Mrigshira, Ashwini, Chitra, Punarvasu are ordinary

c. The rest of the constellations are to be rejected.

d. At the time of nuptials, no planet should occupy the 8th house.
