Polarity exists inside belief structures. I'm speaking more of the subtle yet present varieties that merge with Good vs Evil. Those like: Take it or leave it. Stay or go. Believe or not. The problem many have with religious structure is the inherent inability, in many, to allow outside or personal experience to influence the belief. Unless it conforms to the strict dogma of the religion.
As children we go to where our parents take us and believe what we are told for a certain amount of time before the rebellion sets in. We become imprinted with what we ,at such early ages, are exposed to. This is as you decided it should be, imho. You chose the life, the body, the parents, the time zone, the civilization. You also chose the expanding pattern of probabilities that you would encounter in this life. The options you would choose from. Life's menu. The most certain menu choices were made before you had the ability to choose for yourself in a body.
I say this to say that the Kundalini will bring up the early childhood imprints. Those born to Christianity will see and experience Christian features, the same with Buddha, Allah, Huna, atheist, you name it. These aspects of early childhood are just as important as the state of life you are in right now and the K will expound these traits and experiences. They are not imaginary or phantom features, they are real; Christ, Allah, Buddha, Quan Yin, Mary, Zoroaster, Ahura Mazda, Zeus, Ra, Krishna - they all are real and exist.
This is a Kundalini teaching telling us that not all is as the five senses tell us or that our mind and beta thought patterns present to us. Inside an awakening of the Kundalini these entities can visit you. In real time wakeful life. Sounds nuts but its true. The bad ones can too and we can bless them for the teachings they offer in reverse. They all represent the "Polarity teachings." Once you understand this you can then move on into one-ness.
Religions and the icons of religion, are teachers and deserve our respect, as do those following them. What ever the scenario people are learning at the rate that is best for them at the time in their life that they can learn. Physical plane isn't easy and isn't meant to be. Spirit is very expansive and has much to teach and offer. In many ways it is unlimited so be nice in your thoughts and opinions as they are also actions.
Be respectful and encompassing in your love and respect. For the "All that Is" is you, and you are it. - blessings - chrism
