What we're doing is taming our mind. We're trying to overcome all sorts of anxieties and agitation, all sorts of habitual thought patterns, so we are able to sit with ourselves. Life is difficult, we may have tremendous responsibilities, but the odd thing, the twisted logic, is that the way we relate to the basic flow of our life is to sit completely still. It might seem more logical to speed up, but here we are reducing everything to a very basic level.
How we tame the mind is by using the technique of mindfulness. Quite simply, mindfulness is compete attention to detail. We are completely absorbed in the fabric of life, the fabric of the moment. We realize that our life is made of these moments and that we cannot deal with more than one moment at a time. Even though we have memories of the past and ideas about the future, it is the present situation that we are experiencing.
Thus we are able to experience our life fully. We might feel that thinking about the past or the future makes our life richer, but by not paying attention to the immediate situation we are actually missing our life. There's nothing we can do about the past, we can only go over it again and again, and the future is completely unknown.
So the practice of mindfulness is the practice of being alive. When we talk about the techniques of meditation, we're talking about techniques of life. We're not talking about something that is separate from us. When we're talking about being mindful and living in a mindful way, we're talking about the practice of spontaneity.
We truly cannot experience more than one moment at a time. If we finally take that on board, we will be truly liberated. Being obsessed with either the past or the future causes ongoing suffering. Learning to stay in the present moment - even during times of genuine pain - alleviates that suffering.
