Sagittarius is Guru ki Rashi, so knowledge and learning are naturally important themes for this sign. They are usually people who want to know more and are interested in different subjects. They can have knowledge about several things and are often the ones who keep looking for something new to learn or understand.There is also a certain seriousness in them when they decide that something matters. This can be seen in their work. If they are committed to a particular task, they can be very dedicated towards it and don’t like leaving things halfway when their mind is set on achieving something.The story can be slightly different when the matter is love. Once they become genuinely attached to someone, their reactions can become stronger. They may start taking the relationship very seriously and become more involved with the person. The independent side is still there, but emotions can make them behave in ways that they normally wouldn’t.Impulsiveness is one thing they need to keep in check. Sagittarius can be quick with decisions and quicker with reactions. When feelings are involved, this tendency can become even stronger. Something that bothers them may get an immediate response instead of giving them enough time to think about what actually happened.And then there is possessiveness. A person who usually likes freedom can suddenly want more attention from the person they love. They may want to know where they stand in that person’s life and can become protective about the relationship. This doesn’t necessarily come from a lack of trust every time; sometimes it is simply because their attachment has become stronger.Jealousy can also show up quite easily. If they see the person they love getting close to somebody else, they may not be able to ignore it. Their reaction can come quickly, and they may show that they are upset rather than pretending that everything is fine.For someone with an impulsive side, taking a moment before responding can prevent a small matter from becoming a bigger one.When Sagittarius is serious about you, you may notice the change through these little things. More attention, greater involvement, a protective attitude and sometimes a sudden jealous reaction can say more than words. Their feelings may come with a little intensity, but that intensity is also part of how they express attachment.This article is written by Rinhee Suberwal, an astrologer, Vastu expert, numerologist, crystal healer and tarot card reader.
