According to Osho, gratitude is rare because most people are unconsciously invested in unhappiness. Suffering grants blame, attention, and subtle power learned in childhood, so we cling to illness and misery even while claiming to seek joy. To taste gratitude, one must drop this morbid attachment, accept responsibility for inner states, and prepare for health and happiness rather than rehearsing wounds.
We often hang onto feeling bad because it gets us attention and control, so only those who drop that habit can truly feel thankful.
