First you will have to become aware of the form that surrounds your physical form, and when you have become aware, then help it to grow, help it to increase and expand. What can you do?
Just sitting silently, looking at it; not doing anything, just looking at the bluish form around you; not doing anything, just looking at it, you will feel it is increasing, spreading, becoming bigger and bigger. Because when you are not doing anything, the whole energy goes to the etheric. Remember this. When you are doing anything, the energy is taken out of the etheric.
Lao Tzu says, “Non-doing, no one is stronger than me. Not doing anything at all, and no one is stronger than me. Those who are strong by doing can be defeated.” Says Lao Tzu, “I cannot be defeated, because my energy comes from non-doing.” So the secret is not doing anything.
What was Buddha doing under the Bodhi tree? – not doing anything. He was not doing in that moment. He was not. Just sitting he achieved the ultimate. It looks puzzling. We are doing so much effort and nothing is achieved, and Buddha was not doing anything under the Bodhi tree and he achieved the ultimate.
When you are not doing anything, your energy is not moving out. It goes to the etheric. It is accumulated there. Your etheric body becomes an electric reservoir. And the more it grows, the more you become silent. The more you become silent, the more it grows. And once you know how to give energy to the etheric body and how not to waste it unnecessarily, you have come to realize, you have come to know about a secret key.
Then you can be festive. Really, only then can you be festive. As you are now, drained of energy, how can you be festive? How can you celebrate? How can you blossom? Flowers are part of the luxury. When the tree is overflowing with energy, then flowers come. Flowers are always luxury.
If the tree is starved, flowers won’t come, because even for the leaves there is not enough food. There is a hierarchy: first the roots will be fed, because they are the most basic. If they disappear, then there is no possibility for the flowers. Then the trunk will be fed, then the branches will be fed. If everything goes okay and energy is still there, then the leaves will be fed, and if still the food is there and the tree is totally satisfied and no food is needed, no energy is needed to exist and survive, suddenly it blooms. The overflowing energy becomes flowers. Flowers are a feast for others. It is a presentation. It is a gift from the tree to you.
And the thing happens in man also. A buddha is a tree which has flowered. Now the energy is so overflowing that he has invited all and sundry to come and share.
First try the first technique and then try the second. You can do it separately also, but it will be more difficult to realize the bluish form of the ethereal body.
