If we hear about “something” such as silence and set out to attain it, it will be necessary to take action and make consistent efforts to calm the mind. Having decided that “silence” is desirable, we choose to endeavour for the thing called “silence”, to strive to achieve that desirable state. But by setting a goal, making a choice, and seeking to attain it, we will remain trapped in the mind. The efforts will be mental and as a consequence the results will be mental as well.
