A basic idea underlying Jewish life is that there are no special frameworks for holiness.
A man's relation to God is not set apart on a higher plane; not relegated to some special corner of time and place with all the rest of life taking place somewhere else.
The Jewish attitude is that life in all its aspects, in its totality, must somehow or other be bound up with holiness.
