Twin flames, also called twin souls, are literally the other half of our soul. We each have only one twin, and generally after being split the two went their separate ways, incarnating over and over to gather human experience before coming back together. Ideally, this happens in both of their last lifetimes on the planet so they can ascend together. So you probably haven't had many lifetimes with your twin.
Each twin is a complete soul, not half a soul. It is their task to become more whole, balancing their female and male sides, and ideally become enlightened, before reuniting with their twin. This reunion is of two complete and whole beings. All other relationships through all our lives could be said to be "practice" for the twin, the ultimate relationship.
Have I Met My Twin?
Twin Flame reunions are the most fulfilling relationships we can enter into as humans, on all levels. However, twin flame couples have been extremely rare on the planet, and for good reasons, which will be described later. Despite this, we are finding that more and more twins are finding each other now, because of the acceleration of spiritual transformation and opportunities for soul evolution we are all experiencing. People are evolving and learning and healing at such a fast rate that they are getting ready for their twins faster. What used to take lifetimes to learn and heal, people are now going through in years or even months. This is the astounding level of acceleration we and the planet are going through.
When twins get together, it is for some kind of spiritual service work. This is their primary reason for finding each other, because through their union a huge birthing of creative energy is released, to be used for their mission together. More and more twins are attempting to get together now to help the planet and humanity make a big shift forward in consciousness.
However, many of these attempts at reunion are unsuccessful because the individual people are not quite ready for the intensity of a twin flame union. It is more intense than any other union, and this intensity is at a soul level, not as much in the physical or even emotional bodies. This doesn't mean that there isn't a good attraction at those levels as well, but the strongest attraction is of spirit. This is one of the distinguishing characteristics of a twin soul. Many people think they have met their twin because the attraction is so intense, but it is a karmic attraction, one of need or bodily desire rather than the Divine Love of twins.
Your chance of meeting and staying with your twin depends on how evolved your soul is, and how much of your baggage from this and past lives you have cleared. The biggest reason twins have to separate after coming together is their individual emotional baggage. Because in the presence of your twin, there can be nothing between you, nothing blocking your closeness. This means that everything comes up for healing that you haven't previously healed. Everything!
When twins reunite, both of them experience an acceleration of their spiritual growth and awakening. They get on the fast track of learning about esoteric wisdom and experiencing other states of consciousness. They usually haven't been together all that often during their series of lives on the planet, and so their backgrounds may be different. Yet, there is a closeness and similarities of spirit that are almost uncanny, noticed in many ways, such as looking back at yourself when you look at your mate, and a remembering of the distant past when you first split up. Guidance is strong with these relationships, and usually one or both have a good channel for communication with Spirit. Their connection is telepathic, and hugging each other is like coming home for nourishment.
What is a Soulmate?
Soulmates are our soul family, the ones we do have many lifetimes and experiences with, who help us grow and evolve, create and dissipate karma. According to ancient wisdom, when the soul is "born" or descended from Source, it is created in a group. The souls in this group are our soulmates, ones who are very like us in frequency makeup. Then each of these souls is split into two, creating the twins.
A soulmate is someone you are close to at a soul level, and with whom you have had many shared experiences in different lifetimes, in various kinds of relationships -- siblings, parent-child, best friend, as well as romantic relationships. There is a deep love for each other, and a spiritual bond that sets them apart from the superficiality of most other people in your life. Conversations are generally deep, about personal growth and service to make the world a better place. We can have many soulmates in our lives, and they come to us to help us grow spiritually.
