Here is a discussion of the Spiritual Light that is ever-present and can be perceived, palpably. I mention some ways in which this light can be sensed and how unmindfulness may block this light.
Visible light is a symbol of the spiritual light that is an intrinsic aspect of our awareness. This is my inner experience and I feel passionate about it, for living in this light transforms the negative into the positive.
I hope that you will find this brief talk to be edifying.
