It is one of the urges of our nature to reconnect with Source, with Oneness. The closest we can identify this urge as in daily life is the complete connection with another human being.  To be able to connect with another human being at this level, both parties have to have a very similar vibrational signature.  When we meet another human being with whom we have a similar vibrational signature, we resonate with them. This often is called finding our twin soul, soul mate of twin flame.

It just so happens that when we do find someone like that we stop looking, and therefore the belief that there can only be one soul mate on Earth was conceived.  But, fortunately, there are many other people on Earth with whom we can resonate at a vibrational level. And it so happens that if we change signatures through our soul journey work, if our soulmate doesn't do it too, we will eventually become dissatisfied and move on.  This doesn't mean that our soul mate was not the "true one". It just means they are no longer vibrationally similar to the level we need for the connection.

When two souls meet and embark on Ascension work together, no matter what the modality is, fantastic results can happen.  There are well known couples throughout history that have changed the course of human evolution and path due to their combined power.

It is said, in India, that the true couple doesn't look into each others' eyes, but in fact are looking forward in the same direction, toward the same goal.

Once you enter Oneness, and make it the center of your attention, the urge to connect with another human being at this level passes.  This results in the ability to achieve just that, to find and connect, or reconnect, with a soul mate in total freedom and with no expectations or ego getting in the way.
