Meditation is basically the process of witnessing: looking from your centre all that is happening. Many things are happening on the outside - the noise of the train far away; something is happening in you body - your knees are hurting - right? Your mind is churning many thoughts, that 'What am I doing here?' Your heart is feeling many emotions, you have waited for this moment for so long. There is joy in the heart, a certain ecstasy, a mood, a receptivity. All those things have to be watched very minutely.
