According to Osho, a person can become a Buddha in a sudden leap because 'man' (from manu) means one who can understand. Unlike a seed, a true human can hear, trust, and drop defenses in an instant; years of listening prepare the ground, but awakening flowers immediately when understanding clicks—like Burbank’s cactus sprouting a thornless branch after sustained, loving persuasion.
Because humans can truly listen and understand, and when that clicks, they can change all at once—like a cactus dropping its thorns when it finally feels safe.
