What happens when the sun is in the 10th house and Jupiter is in the 4th house for Leo ascendant?

For a Leo Ascendant, the 4th House is the Zodiac of Scorpio(ruled by Mars) and 10th House is the Zodiac of Taurus(Ruled by Venus)

The 4th House represents our happiness, home, mother, land ownings and home country

The 10th House represents the career that we pursue in life. It also represents the father’s profession

With the placement of Jupiter in the 4th and Sun in the 10th House, the following observations can be made

• The individual’s home environment will be a bit unorthodox and spiritual in nature
• The home environment will put a lot of emphasis on either education or money making
• The individual will be able to choose a career linked to scavenging data for fraud understanding or finding startups to invest in or understanding what is the next big thing in the field of technology
• The individual will be have a keen attention in political developments in their country and will aspire to be joining politics some day
• The individual will meet mentors in their life who might seem to have odd beliefs/rituals but who understand how to deliver results

Hope this gives you an idea

Also, with the Mahadasha of Mars or Jupiter, the results will be much more dominantly visible

All the best

God Bless!
