Ego means self-identification with thinking, to be trapped in thought, which means to have a mental image of "me" based on thought and emotions. So ego is there in the absence of a witnessing presence.
Eckhart TolleSilence is helpful, but you don't need it in order to find stillness. Even when there is noise, you can be aware of the stillness underneath the noise, of the space in which the noise arises. That is the inner space of pure awareness, consciousness itself.
Eckhart TolleAcceptance of what is immediately frees you from mind identification and thus reconnects you with Being. Resistance is the mind.
