And for a disciple thus freed, in whose heart dwells peace, there is nothing to be added to what has been done, and naught more remains for him to do. Just as a rock of one solid mass remains unshaken by the wind, even so, neither forms, nor sounds, nor odors, nor tastes, nor contacts of any kind, neither the desired, nor the undesired, can cause such an one to waver. Steadfast is his mind, gained is deliverance.
