You do not walk your path alone. You are always in a dynamic relationship with the energy of 'other'.
Your inner being vibrates to a specific frequency and has its own evolutionary needs and intent. Relationships are all about frequency co-operation. Union is about harmonizing your spiritual energy with the spiritual energy of the other person.
You attract to yourself the people, places, objects and experiences that resonate with your own energy. The people in your outer world are mirrors for the resonances living inside you.
You will find that when you operate from a place of truth and sincerity, others will do the same around you. This is because you are activating their inner being, you are awakening them to their truth. This heralds the beginning of an authentic, enriching spiritual relationship.
