Experience Total Freedom

Are you stressed? Are you so busy getting to the future that the present is reduced to a means of getting there? Stress is caused by being "here" but wanting to be "there," or being in the present but wanting to be in the future. It's a split that tears you apart inside.
Does the past take up a great deal of your attention? Do you frequently talk and think about it, either positively or negatively? The great things that you have achieved, your adventures or experiences, or your victim story and the dreadful things that were done to you, or maybe what you did to someone else?
Are your thought processes creating guilt, pride, resentment, anger, regret, or self-pity? Then you are not only reinforcing a false sense of self but also helping to accelerate your body's aging process by creating an accumulation of past in your psyche. Verify this for yourself by observing those around you who have a strong tendency to hold on to the past.

Die To The Past Every Moment
You don't need it. Only refer to it when it is absolutely relevant to the present. Feel the power of this moment and the fullness of Being. Feel your presence.
Are you worried? Do you have many "what if" thoughts? You are identified with your mind, which is projecting itself into an imaginary future situation and creating fear. There is no way that you can cope with such a situation, because it doesn't exist. It's a mental phantom.
You can stop this health- and life-corroding insanity simply by acknowledging the present moment.

Become Aware Of Your Breathing
Feel the air flowing in and out of your body. Feel your inner energy field. All that you ever have to deal with, cope with, in real life -- as opposed to imaginary mind projections -- is this moment. Ask yourself what "problem" you have right now, not next year, tomorrow, or five minutes from nöw. What is wrong with this moment?
You can always cope with the Now, but you can never cope with the future -- nor do you have to. The answer, the strength, the right action, or the resource will be there when you need it, not before, not after.
Are you a habitual "waiter"? How much of your life do you spend waiting? What I call "small-scale waiting" is waiting in line at the post office, in a traffïc jam, at the airport, or waiting for someone to arrive, to finish work, and so on. "Large-scale waiting" is waiting for the next vacation, for a better job, for the children to grow up, for a truly meaningful relationship, for success, to make monëy, to be important, to become enlightened. It is not uncommon for people to spend their whole life waiting to start living.
Waiting is a state of mind. Basically, it means that you want the future; you don't want the present. You don't want what you've got, and you want what you haven't got. With every kind of waiting, you unconsciously create inner conflict between your here and now, where you don't want to be, and the projected future, where you want to be. This greatly reduces the quality of your life by making you losë the present.
For example, many people are waiting for prosperity. It cannot come in the future. When you honor, acknowledge, and fully accept your present reality -- where you are, who you are, what you are doing right nöw -- when you fully accept what you have got, you are grateful for what you have got, grateful for what is, grateful for Being. Gratitude for the present moment and the fullness of life now is true prosperity. It cannot come in the future. Then, in time, that prosperity manifests for you in various ways.
If you are dissatisfied with what you have got, or even frustrated or angry about your present lack, that may motivate you to become rich, but even if you do make millïons, you will continue to experience the inner condition of lack, and deep down you will continue to feel unfulfilled. You may have many exciting experiences that monëy can buy, but they will come and go and always leave you with an empty feeling and the need for further physical or psychological gratification. You won't abide in Being and so feel the fullness of life nöw that alone is true prosperity.

Give Up Waiting As A State Of Mind
When you catch yourself slipping into waiting... snap out of it. Come into the present moment. Just be, and enjoy being. If you are present, there is never any need for you to wait for anything.
So next time somebody says, "Sorry to have kept you waiting," you can reply, "That's all right, I wasn't waiting. I was just standing here enjoying myself -- in joy in my self."
These are just a few of the habitual mind strategies for denying the present moment that are part of ordinary unconsciousness. They are easy to overlook because they are so much a part of normal living: the background static of perpetual discontent. But the more you practice monitoring your inner mental-emotional state, the easier it will be to know when you have been trapped in past or future, which is to say unconscious, and to awaken out of the dream of time into the present. But beware: The false, unhappy self, based on mind identification, lives on time. It knows that the present moment is its own death and so feels very threatened by it. It will do all it can to take you out of it. It will try to keep you trapped in time.
In a sense, the state of presence could be compared to waiting. It is a qualitatively different kind of waiting, one that requires your total alertness. Something could happen at any moment, and if you are not absolutely awake, absolutely still, you will miss it. In that state, all your attention is in the Now. There is none left for daydreaming, thinking, remembering, anticipating. There is no tension in it, no fear, just alert presence. You are present with your whole Being, with every cell of your body.
In that state, the "you" that has a past and a future, the personality if you like, is hardly there anymore. And yet nothing of value is lost. You are still essentially yourself. In fact, you are more fully yourself than you ever were before, or rather it is only now that you are truly yourself.
The past cannot survive in your presence. Whatever you need to know about the unconscious past in you, the challenges of the present will bring it out. If you delve into the past, it will become a bottomless pit: There is always more. You may think that you need more time to understand the past or become free of it, in other words, that the future will eventually free you of the past. This is a delusion. Only the present can free you of the past. More time cannot free you of time.
Access the power of Now. That is the key. The power of Now is none other than the power of your presence, your consciousness liberated from thought forms. So deal with the past on the level of the present. The more attention you give to the past, the more you energize it, and the more likely you are to make a "self" out of it.
Don't misunderstand: Attention is essential, but not to the past as past. Give attention to the present; give attention to your behavior, to your reactions, moods, thoughts, emotions, fears, and desires as they occur in the present. There's the past in you. If you can be present enough to watch all those things, not critically or analytically but nonjudgmentally, then you are dealing with the past and dissolving it through the power of your presence.
You cannot find yourself by going into the past. You find yourself by coming into the present.
