Because your Twin Flame challenges you since you share the same equal energy vibration. They are the other part of your Soul – your Twin Flame will change you and intimidate you – they know how to press your emotional buttons since you are one Soul.
When it comes to my Twin Flame, I have no guard, I open my soul to him without any hesitation – and I can trade my life for his in a heartbeat.
The Twin Flame Love triggers all the pain within you so that you can have a cleansed Soul.
In order for Twin Flames to match and unite in energy vibration, all the emotional pain within you is triggered so that you have room to House the unconditional love that you share with your Twin Flame.
It is true that the Twin Experience is spiritual – for physical Union to occur, your Spirit has to be in alignment with your Twin Flame shared energy. This is why you both go through a period of energy cleansing.
