When you are hurting and empty it is good to fill yourself up with the light and/or God. The light is crystalline clear. God can offer comfort and solace.
At some point in this life the emptiness filled by the fleeting light or by God will have to be filled by what is in life. This will last for a time. Sadly once this is done and we become attached to it we have to say goodbye and once again become refilled by the light of God.
