According to Osho, to put everything at stake means withholding nothing—drop all tricks, calculations, and even reliance on your own intelligence. Stand naked before truth, admitting your mixture of good and bad, and surrender entirely to the Master/existence: no back doors, no conditions, no bargaining. Such total guilelessness and trust allow real transformation, whereas cleverness only makes you miss.
Stop being clever or hiding anything—trust completely and show up exactly as you are, letting truth guide you.
