Only when one is connected to one's own core is one connected to others; the core, the inner spring can best be refound through solitude.
When you turn within you think you see a light. What you think is the light that you see in the inner world is the light that sees, not the light that can be seen. This is a different kind of light, not the kind of light that can be radiated from a source. This is the all-pervading light. Think of yourself as that light, then your aura will burn more brightly.
