Kundalini shakti creates our mirror, develops it and cleans it. Slowly She makes it capable of receiving in itself the reflection of Atma (the Spirit). In Sahaja Yoga you know that awakening of Kundalini is very easy and spontaneous. But Sahaja Yogis must know that they have come to Sahaja Yoga primarily to clean their mirror, to wash their sins and past deeds, to become purified of all the dirt that has been accumulated within from time immemorial. They have not come to collect sins and dirt, but to become pure. Many Sahaja Yogis are aware that Kundalini is that current which passes through their Chakras and awakens their Chakras. When the light comes on your Chakras you can know their condition even on your finger tips.
This is the knowledge. This alone is to be known. So far the knowledge that you have had was not enlightened. There was no light in it. Now because of the light, you can know which of your chakras have problems. There is a way to clear the Chakras of those problems. How to do it, is also taught in Sahaja Yoga.
