The work I do with Ayurveda and Yoga puts a great deal of value on living naturally and simply. Between long work days, overplanned schedules, and a dependence on high technology, most of us in the modern world live a life that embodies neither of these qualities. But, it is when we live in greater balance with nature that we fully realize our greatest purpose and potential.
If living a healthy life requires you to take on radical change, then it is really only because of the nature of the life you are living to begin with. If cutting out coffee and sugary soft drinks, eating whole foods grown locally, remaining physically active, and creating a daily routine of spiritual growth seem radical to you, then there's a very good chance you will benefit from such a revolution in your life.
