1. Irresistible Force - There's nothing on earth that can prevent them from meeting, no matter where each maybe located on planet earth. They will surely meet. No social, moral, political, racial, legal or religious barrier can set them apart. They maybe years apart in age, but is important in a soulmate encounter is that they have the same soul age or same pattern of soul evolution.
2. Absolute Certainty - Both will recognize each other from the very depths of their soul or being. Sometimes their mind or intellect may fight the soul recognition because of social or religion considerations. But deep in their very souls, they know that they are meant for each other. In a true soulmate encounter there is at once soul recognition by both partners. They know they met their other half.
3. Relationship is Total - Most of our relationship with others are not based on the totality of our being. Here, one will relates to the other the totality of his being: the relationship is at once physical, etheric, emotional, mental, astral and spiritual with the mental and spiritual levels playing a more important role compared to the other levels. The is why a soulmate encounter is so strong and so irresistible.
4. Absence of Guilt - Because of centuries of religious teachings based on fear, sin, eternal damnation, people grow up having a lot of guilt feelings. A very strong attraction one has towards the opposite sex can be mistaken for mere lust. But in a real soulmate encounter, there is no feeling of guilt at all. You are sure it is the right thing to do or its the proper feeling, no matter what the circumstances are.
5. Soul Expanding - A soulmate helps you in your soul evolution. One leads to God and to your spiritual destiny. He/she helps you to achieve faster the soul evolution and awareness.
Why do we seldom meet our soulmate? One may find themselves married to non-soulmate?
* The simplest answer is Karma. We still have to work out for karma with other individuals before we are ready to meet our soulmate. He/she will come when the time for your meeting is already at hand. You may have decided this in previous lifetime together with your soulmate.
