When we're being grateful it means that we're acknowledging that life is a gift, that life is a blessing, that this body is only here for a short period of time and it really shifts the whole internal landscape of the mind and it puts things into perspective and it allows us to get our bearings. To get a firm footing in what's real, and then go from there.
The happiness of life consists, like the day, not in single flashes (of light), but in one continuous mild serenity. The most beautiful period of the heart's existence is in this calm equable light, even although it be only moonshine or twilight. Now the mind alone can obtain for us this heavenly cheerfulness and peace.
Let Pascal say that man is a thinking reed. He is wrong; man is a thinking erratum. Each period in life is a new edition that corrects the preceding one and that in turn will be corrected by the next, until publication of the definitive edition, which the publisher donates to the worms.
There should be a period of time during each practice session when you perform. Invite some friends in to your practice room and play a passage or a page of something. . . . What I'm trying to indicate is that each day should contain some amount of performing. You should engage in the deliberate act of story telling each day you practice. Don't only gather information when you practice, spend time imparting it. This is important.
