The dominance of satva, rajo or tamo in a chart, too helps in determining native's overall worldly life pattern. Dominance of Satva may too hint at troubled early life - but with the age, they find more peace, prosperity and satisfaction. (primarily Sun/Moon are key).

For example - there are sato dreshkona - first one on moveable sign; second one in fixed; and third one in dual sign. If native is borne in sato drehkona - then his chart gains strength. It doesn't mean that he may not have struggles, but eventually chart will have core strength.
