Vulnerability is not a weakness, a passing indisposition, or something we can arrange to do without, vulnerability is not a choice, vulnerability is the underlying, ever present and abiding undercurrent of our natural state. To run from vulnerability is to run from the essence of our nature, the attempt to be invulnerable is the vain attempt to become something we are not and most especially, to close off our understanding of the grief of others.
Silence is powerful; it must be approached with sensitivity. There are times when silence during a meal may be important, while at other times it may be a hindrance. Silence at meals is interesting to explore; many find it increases the energy obtained from the meal. But beware. A little silence in a noisy culture is revolutionary; you may learn to love it. If that happens, share your silence with those who also love silence.
