When the times bring you to that place where you feel unworthy of love and divine grace, think about the love parents have experienced for their child.
When immersed in remorse for past deeds, or when feeling weakened by the chains of habit in the sleeping state, think about the love present when you see a child you love. You do not love him for his strength, his power, or his abilities. You love him for the essence in him. If he is sleeping, you love him the same as when he is awake.
So is the light of your heart; worthy of love divine even when you are trapped in the sleeping state.
The mother sings to the child, though in his sleep the child knows it not, and his small breath is enough for the mother to feel all her loving care rewarded. That divine breath in you, makes your heart love, and that love comes from the infinite in you, and that awakens the love of the supreme consciousness witnessing your heart of hearts.
In the source of that love, no merit or deed is needed to justify it. Its existence is its reason to be loved.
