The self-destructive force in us can be so strong that it is difficult to be friendly to ourselves. The self-destructive feelings can really overwhelm us. This is why awareness is so important in the practice of meditation. When you realise that you have this self-destructive tendency, and this aspect arises together with the minuses, you should immediately catch it. You realise that it is a very strong tendency, a strong conditioning, a habit. It is important to realise that it is only a habit, it is only a conditioning. It is not representing something real. When you see it as a habit you don’t give it such a power and energy as when you take it as real.
A very interesting exercise is to ask yourself every day: “How many minuses have I given myself today?” Then try and see also the differences in the minuses you are giving yourself: big ones and small ones. Finally, rather than feeling bad about it, you can laugh at it. Then there is a lightness and even a joy. In the practice of meditation I think it is very important that we work with ourselves in a light-hearted way, even with our shortcomings, rather than be heavy, beat ourselves, or be very serious and intense.
