Undertaking regular spiritual practice helps make our minds and intellect spiritually purer so that we can make better decisions for both ourselves and the well-being of society. Chanting the Name of God is the easiest way to overcome the sin incurred because of the killing of plants and microorganisms in our day-to-day life. At the spiritual level of 60% and above, one has a greater communion with God. Beyond this spiritual level, chanting continues to take place (at a non-verbal level) throughout the day in the sub-conscious mind. Chanting at this advanced level automatically absolves us from minor sins incurred by killing various living beings such as plants and insects throughout the day.
