Buddha says: Meditation brings two things. It brings wisdom, it brings freedom. These two flowers grow out of meditation. When you become silent, utterly silent, beyond the mind, two flowers bloom in you. One is of wisdom: you know what is and what is not. And the other is of freedom: you know now there are no more any limitations on you, either of time or of space. You become liberated. Meditation is the key to liberation, to freedom, to wisdom.
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.
The essence of all slavery consists in taking the product of another's labor by force. It is immaterial whether this force be founded upon ownership of the slave or ownership of the money that he must get to live.
