Thinking is what a great many people think they are doing when they are merely rearranging their prejudices.
Over the last twenty years, I have been forced to recognise that I spend far too much of the time when I attempt to meditate, sitting on my cushions lost in thought. This thinking is rarely helpful.
These thoughts, that insistently intrude upon my practice, and which come so regularly and without any formal invitation, fall into three main groups. There are variations on the themes that are involved, and in the content that they cover. The one thing that they have in common is to increase the irritability and reactivity of the mind.
