According to Osho, inner voices from society and teachings must first be countered with a conscious 'thorn'—a master's words—to uproot old conditioning, then even that aid must be dropped. Respect the guide, but don't carry the raft. Ultimately, free yourself from all borrowed voices so a wordless, unclinging awareness—no-mind—remains. This 'kill the Buddha' courage is the highest respect.
Like using one thorn to pull out another, use guidance to quiet noisy thoughts—then throw away both thorns and rest in simple inner silence.
