Your soul is not becoming light. It has always been light.
Nothing needs to be added to your soul, for it was born from the Infinite already whole and radiant.
What you call awakening is simply the gradual removal of fear, limitation, and false identity that have obscured your true nature.
As these layers dissolve, your light shines naturally.
You stop striving to become spiritual because you realize spirituality is not something you practice; it is the essence of what you are.
The sun does not struggle to shine, and neither does the awakened soul. ~KejRaj
