The blemishes of the heart have to be washed by leading moral life and doing one's duty. A time may come when you become tired or weak - If it is, then you should pray thus: "Oh Lord, things have gone beyond my capacity. I feel further effort is too
great a strain. Please give me strength." At first, God stands at a
distance, watching your efforts like the teacher who stands apart when
the student writes the answer to his questions. Then, when you shed
your attachment to enjoyment and take to good deeds and service, God
comes encouragingly near. For, He is like the Sun God, who stands
waiting outside a closed door. Like the servant who knows the rights
of the master and his own limitations, God does not announce His
presence or bang the door. He simply waits! When you open the door
just a little, the Sun rushes and promptly drives out the darkness
from within. So too, when God's help is asked for, He is present by
your side, with his Hands extended to render assistance. All that is
needed is the wisdom to remember Him and the discrimination to pray
and ask Him.
