Shukra (Venus) mahadasha for Tula (Libra) Moon sign

In the Vimshottari system a life moves through nine long periods, each ruled by one planet. The planet that rules the period sets the tone of those years: the areas of life that come forward, and the kind of effort that pays.

The Venus mahadasha lasts 20 years in full. Most people meet it partway through, so the part they live through can be shorter.

Venus stands for love, partnership, comfort, beauty and the arts. Its period tends to bring relationships, pleasant surroundings, creative work and the things that make life comfortable.

Counted from Libra as the first house, Venus rules Libra and Taurus, your 1st and 8th houses. During its period the matters of both come forward:

The 1st house is you yourself: your direction, confidence and the way you meet the world. Its lord's period tends to put you at the centre of your own story and to favour fresh starts you choose for yourself.

The 8th house is sudden change, shared money, in-laws and hidden matters. Its lord's period tends to bring turns you did not plan, joint finances to sort out, and an interest in research and what lies beneath the surface.

Venus is itself the lord of Libra. Its period tends to feel close to your own nature, and what it brings is usually easier to own and make use of.

Which mahadasha you are in, and when it began, depends on the Moon's nakshatra at the moment you were born, so it is personal to you. Even within the Venus mahadasha, where the planet sits in your own chart and the sub-periods inside it shape the years more than your Moon sign alone.
