When you are in office – amidst all sorts of distractions – and you want to experience one-pointedness, there are techniques for this. The technique is to couple the mind with some action.

Similarly, we cannot sit without any thought. Instead of focusing on thoughts from the outside, we substitute it with the thought of breath.
