Perspiring is good for your health. But perspiring physically, i.e. sweating, is not enough, and do not be surprised if I tell you that the soul and the spirit must also perspire. Love makes the soul perspire and wisdom makes the spirit perspire. Of course the word perspiring must be understood in a very wide sense.
Perspiration symbolizes a perfect exchange that is established between the microcosm (humankind) and the macrocosm (the universe). Physically, these exchanges occur through the skin, as we discard waste and absorb energy through the skin. In the subtle plane, however, these exchanges occur through the aura, which is our spiritual skin. So, if I say that, like our physical body, our soul and our spirit must also perspire, I am referring to the exchanges we must make in the subtle planes with divine wisdom and love.
