In the end, meditation is not about exotic sages, black robes, and following in the footsteps of someone else.
Which means that the definition of the opposite of meditation might be: “to be a toddler.”
But what starts out as an angry letter to an air carrier becomes a meditation on his layover in life.
c.1200, "contemplation; devout preoccupation; devotions, prayer," from Old French meditacion "thought, reflection, study," and directly from Latin meditationem (nominative meditatio) "a thinking over, meditation," noun of action from past participle stem of meditari "to meditate, think over, reflect, consider," frequentative form from PIE root *med- "to measure, limit, consider, advise, take appropriate measures" (cf. Greek medesthai "think about," medon "ruler;" Latin modus "measure, manner," modestus "moderate," modernus "modern," mederi "to heal," medicus "physician;" Sanskrit midiur "I judge, estimate;" Welsh meddwl "mind, thinking;" Gothic miton, Old English metan "to measure;" also see medical).
Meaning "discourse on a subject" is early 14c.; meaning "act of meditating, continuous calm thought upon some subject" is from late 14c. The Latin verb also had stronger senses: "plan, devise, practice, rehearse, study."
