According to Osho, repeating a mantra from a saint cannot produce liberation if it is pursued as something to get. Liberation is not an achievement but an unveiling of what you already are, realized instantly when greed and the inner race stop. Mantras, austerities, and techniques become spiritual shopping; drop the grasping and rest in suchness; then freedom reveals itself.
Chanting won’t free you if you’re chasing a reward; stop grasping and relax now, and your built-in freedom shows up.
