Vasumathi yoga mainly related to wealth.
The yoga is formed when benefic planets occupy 3,6,10,11 houses either from Ascendant or moon.
From Ascendant, if all four (Jupiter, Venus, Mercury, and Moon) benefics occupy 3,6,10,11 houses then only full results of the yoga are possible.
From exalted or well placed waxing moon, remaining 3 benefics should occupy 3,6,10,11 houses to get full results of the yoga.
A true Vasumathi yoga is very rare.
Also, if Jupiter is placed in 6th house from moon, it causes shakat yoga which makes native penniless, quite opposite to Vasumathi yoga. Hence, Jupiter should not be posited in 6th from moon.
Strong Vasumathi yoga is formed when exalted benefics occupy 3,6,10,11 houses. As per sage Parashara, in Chandra-yoga-Adhaya, to get full benefits of yoga which is indicative from Ascendant, moon should not be hemmed between evil planets by causing paap-kartari-yoga.
