According to Osho, attachment to a teacher breeds expectation and dependence; therefore a real master deliberately 'breaks your heart'—shattering clinging, promises, and consolations—so your closed heart opens to its own emptiness. He refuses to be a security blanket, undermining your projections until you ripen into understanding beyond life and death, discovering freedom that does not rely on the teacher’s presence.
Clinging to a guru makes you dependent; a true one will shake you free so you find your own inner space.
