You need not stop working or give up your jobs and duties. You only have to cultivate the noble attitude of offering everything you do to God. Imprint in your heart the thought that all you do should be acceptable to God. Faith is essential. Wihtout it nothing can be accomplished.
Faith is extremely important.
What breath is to a human body, faith is to spirituality. Devotion without faith is as useless as a body withut breath. Therefore, it is said that the bull without a yoke, the horse without reins, the car without brakes, and a man without sense- control are useless. Chanting of the Lord's name is essential to go across the sea of bondage. The name of the Lord is a boat.
