please give general prediction for Venus in Uttarashadha nakshatra?

Sign of Capricorn is the natural sign on karma assigned to you. Whichever planet is in Capricorn, you’ll be forced to serve that planet/ it’s significations. So generally, be helpful to women, people in hospitals, ashrams, lonely people, nature. If your Venus is affected by malefics or ashtavarga points are less then you might get into trouble with women/spouse so be careful. 3rd house is also subconscious mind so you might be thinking about career, money, women, siblings, neighbous etc. You can have artistic hobby that can be your career, other factors need to be checked. If this is this combination is giving you difficulties then do Gajendra Moksha Stotram, you can get it on YouTube.
