According to Osho, 'knowledgeable' people are compared to parrots because they merely repeat borrowed words without living, conscious experience. Their minds are stuffed with secondhand facts, yet the 'man'—awareness—has not arrived; they function like computers, not beings. He even calls it unfair to parrots, who at least display intelligence, while scholars mimic mechanically, mistaking information for wisdom.
They just copy and talk like a recorder, not from their own seeing or feeling.
