Prana is multidimensional, so a mask will not obstruct the flow of this energy. While air is a medium for Prana, such force exists within the water, earth, and fire as well, not just the air. We assimilate Prana through our senses, thoughts, attitudes, impressions, and even consciousness. Air is just one way that Christ gives life.
Joyful in hope, suffering in tribulation, be thou constant in thy prayer.
Benedictis, qui venit in nomine Domini. Osanna in excelsis.
"Blessed is he who comes in the name of the Lord. Hosanna in the highest!"
