Sri Lalitha Sahasranamam 1.1

When we chant we use our vocal apparatus to produce the sound. The process brings us into the eternal NOW. When we write, a long lapse of time can pass between the time of writing and our re-reading. When we chant, the action brings us in the present moment. The process of chanting demands full attention, at least on the physical level. There is also the question of resonance. Chanting evokes and invokes resonance in letters and words. All mantra can be chanted in three forms, the vachika form(chanting externally, uttering sound) is the between, and the lalitha is the grossest.Yet, this requires full knowledge of what one is doing. It follows that when we chant we are in the NOW, we are vibrating, and we know what we are uttering so that when we move to the subtlest plane.
