From Volume 15, The Notebooks of Paul Brunton.
Be present at your thinking and breathing and feeling and doing. This is what the Buddha called “mindfulness.” But the highest possible form of mindfulness is to be present with the Overself for, after all, the other four are concerned with the ego, even though they are attempts to free yourself from it, but here it concerns that which completely transcends the ego. 15.6. 236
When activity of any kind, in work or leisure, takes place in this atmosphere of remembrance, it becomes sacramental even though the ordinary observer may not know it. 15.6.243
To keep up this remembrance all the time, in all circumstances, requires practice and perseverance to an extent that seems beyond the ordinary. But they are actually within everyone’s untapped resources and untouched reserves. 15.6.244
