Ordinary people are in dark about God, spiritual welfare. Sages are in dark about material world, its pleasures.

To a family man consciousness means gathering material things, things which will give him a more prosperous, secured life. This is his awakening, his day, his real world. He is completely in dark about God and his own spiritual welfare. He is asleep about them, they don’t exist to him.

But to a sage God and his spiritual welfare is the light, daytime, he stays awake in these needs, that is, strives for these things. He is completely asleep about his material welfare.. property, money etc. They don’t hold any importance to him because they are fickle to him. They are illusion to him. Illusions which try to keep him away from his spiritual welfare, surrendering to God. hence he is in dark about them.

So the side of mind which is asleep in social man (god and spiritual self) is awake in sage, and the side of mind which is awake in family man (material world, money etc) is asleep in the sage.
