Because everything manifested is creation of the original transcendental Sound, therefore, factually everything is spiritual. But being covered by material cloud, we do not appreciate properly the spiritual nature of everything. The Krishna Consciousness Movement means gradually advancing towards that stage of spiritual realization. As such, the philosophy of acintya bhedabheda tattva is perfect. Everything is simultaneously one and different from the Supreme. One in quality because the original source is the Spiritual Whole, and different in quantity. This quantitative difference becomes more and more separate by increase of material consciousness.
