These spiritual masters understood that a spirituality that begins in the acceptance that one is not "in control" necessarily involves a flexible attitude, which requires a mistrust of the rigidities of certainty. If life is "unmanageable"—and, of course, at time it is—there will necessarily be sudden surprises, unexpected twists and turns, unforeseen detours. In recognizing spirituality's—life's—open-endedness, we learn to be flexible and adaptable, thus protecting ourselves from the tendency to want to fix things "once and for all." Hold fast to the "now" means "hang on and enjoy the ride," for we never know (and we can't control) where the vicissitudes of the pilgrimage that is spirituality will take us.
The modern mind—so enthralled by technique, so oriented to efficient production and "bottom-line" results, so obsessed with comfort and predictability—approaches the concept of pilgrimage with wariness and puzzlement. Why backtrack and sidestep when you can march straight ahead? The word vicissitudes, with its promise of ups and downs, its suggestion of successes and failures, its reminder that we cannot "march straight ahead," is unsettling and disorienting for those who equate progress with perfection.
