Karma is not something pessimistic. If you think of karma as something wrong, you are seeing karma only according to what happened in the past. You look at the past and karma becomes a monster. So you should also look at karma in the present and future. Then karma becomes something very wide and really alive. Through karma you can understand what your destiny is. Destiny itself has no solid form; it's something you can create. You can create your life. That is why we study karma.

The moment between before and after is called Truth.

Spiritual security means you are fully alive and comfortable in your life as it is, without expecting anything.

You have to do your best to face every moment, because this moment will never come again. The moment that you are living right now is a very important opportunity to make your life vividly alive. If you want to live with spiritual security in the midst of constant change, you have to burn the flame of your life force in everything you do.

If you want to find Buddha nature, love someone and care for them.

Make positive effort for the good.

Be present, from moment to moment, right in the middle of the real stream of time. That gives you spiritual security. That is why in Buddhism we don't try to escape from impermanence; we face time itself in our daily living.
