The human energetic field is built of layers (Koshas). They are present and surrounding us regardless of whether we are awake to the experience. The science of Yoga sensitizes the practitioner to become aware of how becoming aware of and cleansing one layer reveals the next. The process continues until Self-Realization occurs…eventually. But, how can we notice something that we are presently unaware of? The use of the 20 Gunas described in Ayurveda, can define small experiences that speak to seeing that which was previously invisible.
