Dag Hammerskjöld (1905 ~ 1961) said, “We all have within us a center of stillness surrounded by silence.” Yet, for some, silence and stillness are elusive. Caught up in the hustle and bustle of daily life, they find it difficult to drown out the clamor swirling about them. Even if they can retreat to a quiet spot, there is still the endless chatter in their minds to deal with.
