Your first name of Siyanu has given you a practical, efficient, and capable nature, with a desire to participate in business ventures. There are times when you experience stress and discontent. You tend to be somewhat unbendable in your opinions, which are usually arrived at through much analysis on your part. Mathematical studies, technical fields, and scientific topics interest you. You are happiest with others who share your practical, sensible qualities. A difficulty in expressing affection causes you to show your love for others by what you do for them rather than what you say. As you are not spontaneous, you need time to gather the facts and think through a situation logically before you can handle it. You dislike leaving anything unfinished or untidy. It is difficult for you to merge your nature with others to create understanding, or to show love and tenderness to those close to you. Other health weaknesses could affect your reproductive system causing difficulties with childbirth.
