Yours Affectionately

The more time you devote to meditation, the more distinctly you will hear the sound current, which makes for peace of mind or, as you put it, helps us in chaining the monkey.

I am glad to read that your meditation is improving. For ages the mind has been developing an intense longing for the things of this world which ostensibly satisfy it for some time but cease to do so after a while. The best way to divert the mind from the mundane baubles is to give it a taste of the inner bliss which far transcends any earthly joy. This inner bliss can be attained by going in and listening to the inner Sound constantly or at least for as long as is possible every day. This is how the monkey can be effectively chained.

I am glad that you consider meditation the most important business in life. You should increase your time for meditation. It should not be for less than two and a half hours at a stretch, whether the mind takes interest in meditation or not. Sometimes the mind avoids it on petty excuses. When it behaves like this it should be punished by increasing the time that day by another half-hour. With the increase in time, the concentration will be complete, the attention will go in, and the sound current will be your constant companion, giving you joy and peace.
