Silence foreshadows and houses that fertile consciousness of Being (the unitive state) within all of us. Progressively, silence calls us into this awareness, until at some point we live in it, or realize it lives us. Then, each leaf, flower or bud reminds us of that Heart or Reality or Void in which we all have our life and being.
Conscious labor and intentional suffering are not so much separate practices as twin pillars of what amounts to essentially a single spiritual obligation.
Conscious labor is basically any intentional effort that moves against the grain of entropy, i.e., against that pervasive tendency of human consciousness to slip into autopilot. It means summoning the power of conscious attention (in our era perhaps more widely known as 'mindfulness') to swim upstream against that pervasive lunar undertow drawing us toward stale, repetitive, mechanical patterns, the siren call of World 96.
