Core Insight:
According to Osho, Patanjali’s dhyana is one step within an eightfold, gradual discipline, whereas in Zen (za-zen) meditation is the sole and sufficient step aimed at sudden awakening. Patanjali offers a complete staircase; Zen is the leap. Both are valid, but choose by your nature: cautious types progress stepwise; risk-ready souls can drop all else and just sit.
