I hope to gain some insight into istikhara signs after dua. I made an istikhara last night on something this morning something happened to make my goals for the thing I prayed iatikhara for easier. Can one interpret that as a positive sign?
As per my knowledge, yes it is a positive sign. Usually after istekhara you find it easy to attain the goal or there come such situations that you let go of it
when we perform istikhara we depend on Allah (Swt) to make the decision on behalf of us. So when we proceed to do a task then if Allah find that out good for us then He will ease that task for us otherwise obstacles will be their.
Tanslation of istikhara Dua is given: TRANSLATION: "O Allah! I seek goodness from Your Knowledge and with Your Power (and Might) I seek strength, and I ask from You Your Great Blessings, because You have the Power and I do not have the power. You Know everything and I do not know, and You have knowledge of the unseen. Oh Allah! If in Your Knowledge this action (which I intend to do) is better for my religion and faith, for my life and end [death], for here [in this world] and the hereafter then make it destined for me and make it easy for me and then add blessings [baraka'] in it, for me. O Allah! In Your Knowledge if this action is bad for me, bad for my religion and faith, for my life and end [death], for here [in this world] and the hereafter then turn it away from me and turn me away from it and whatever is better for me, ordain [destine] that for me and then make me satisfied with it."
Yes, you may interpret it as a positive sign, but know that your answer to an istikhara isn't always going to become manifest in your life. You will NOT necessarily see a dream/vision/sign/etc. Allāh ﷻ will place a bit of inclination in your heart towards going through with the action or not (source)
