The darkness of the mind disappears when God is realized. In the Purana it is said that it was as if a hundred suns were shining when Rama entered the court. Why, then, weren’t the courtiers burnt up? It was because the brilliance of Rama was not like that of a material object. As the lotus blooms when the sun rises, so the lotus of the heart of the people assembled in the court burst into blossom.
The human mind is like a package of mustard seeds. As it is very difficult to gather the seeds that have escaped out of a torn package and are scattered in all directions, so too when the human mind runs in diverse directions and is occupied with worldly things, it is not a very easy task to collect and concentrate it.
The huge jar kept under water is completely filled and gets immersed on all sides. It does not gurgle anymore and remains completely silent. Similarly, the soul immersed in God perceives nothing but the all-pervading Spirit within and without and knows only the deep peace of inner communion.
