The 3D paradigm is where separation, linear time, fight/flight, blame/shame, good/bad luck, social status, competition, matter, not having enough, not being enough, not enough to go around, attachment to body/physical form exists.
When we raise children to focus on matter Vs energy, we teach them that they need to be "someone" or "somebody". We teach them that they need to get "somewhere" or be "someplace". We teach them they need to "have" things or "own" things in order to be happy, successful and fulfilled.
Raising 3D kids perpetuates the 3D paradigm which the ego loves - but the soul can not grow in this dimension. Help move society into the 5D by teaching your children about energy: they/we are energy. Teach them that they are no one, no thing, and no where, that they are everyone, everything and everywhere - beyond time and space. Teach them that they are consciousness. This is our contribution to evolving society and healing humanity.
Loneliness
Loneliness has nothing to do with partnership and everything to do with relationship with the self. Loneliness comes from an accumulation of abandoning, rejecting, neglecting the self. Not listening, not valuing, not honoring the self: your truth. Loneliness cannot be cured by others. If you find yourself wanting a relationship because you are lonely, it is best to fill your own "love bucket" by doing all the things you want to do, for yourself. When you become responsible for your wholeness and completion, you will no longer attract others who abandon, reject and neglect you. You won't need them to compensate that which you refuse to do for yourself. For everyone mirrors your relationship with your self. The cure for loneliness is you, and no other. Whatever it is you want a partner to do for you - you get to do it for yourself.
