Tracy's third question via email:

3. Why do we have chemistry / connection with some people and not others? What is the purpose of people coming into our lives?

Answer, for discussion: On a base level we are drawn to others by the chemical makeup in our scent. This can become confused due to the use of perfumes, deodorants and shower gels etc disguising our natural scent beneath these added scents. It’s a natural instinct of humans just like any animal, to be drawn to someone’s scent.
On a spiritual level we are all teachers/students of each other and each allowing the flow of giving and receiving; a shared teaching/learning experience. Everyone in your experience has something to teach you. Appreciating the value in all others allows us to expand ourselves, to expand our field of love, to grow alongside and with others. To exclude no one as no one is excluded, all are inclusive of this process, is what allows us to learn and grow completely. Every relationship has the opportunity to become a Holy/Whole relationship. Whether that be passing someone in the street and offering a smile, a relationship with a shop keeper or a more long term relationship. The shared teaching may not even seem like a friendly relationship but it is a relationship non the less. It’s my opinion that when the feelings of a connection are involved these are relationships that have a deeper involvement in the learning experience. For example: You may have asked to be shown how you can overcome a fear of a particular experience or mind pattern. These people who present themselves to you with you having that feeling of having known them, or being drawn to them in some way, is because you have asked to meet them, and it is the recognition of these teachers that feels like an ultimate connection – because basically they are given in order for you to be shown.
