The heart can sense the outside world with much more than the five senses provide and can know and understand much than is considered invisible, or beyond the five senses.
The heart can also sense every organ inside the human body and respond to the needs of respiration, circulation, nutrition and all of the bodily systems. The highly developed heart can assume the autonomic aspects of the cardiovascular system and control circulation, respiration and many other aspects of maintaining internal equilibrium.
The pulse of the heart is the voice of the divine, both inside and outside of the human being. Heart perception is far beyond what science understands about this Holy Grail of human consciousness.
Each individual is responsible for creating his own world by bringing what is inside of him to the perception of what is outside of him, and then determining his relationship to those perceptions for good or ill. Finding the bridge between the inner world of a thinker and the outer world of perception is the key to philosophy and the science of knowing. Perception gives us a chance to “know” something about the world and our relationship to it. But the real question is: What can the observer know?
Suffering is here to create the chance to become free of attachment to the outside world. Every challenge is another opportunity for the giftedness in each of us to unfold.
Spiritual development is about integrating the inner with the outer and finding the wisdom in both. To find wisdom, we seek all the places where life springs forth anew. Living-thinking springs from a heart that has “warmed up” thinking. This higher thinking, Imagination, has the power and brilliance to see “into” things, both within the self and in the outer world around us. Burying our head in the sand or withdrawing into our shell doesn’t advance spiritual development; it is interaction between the inner and the outer that quickly develops the soul and spirit.
