By what laws, the System of the Universe is operated?
Can you see that this question is the product of thinking? Any answer will simply satisfy or dissatisfy you. It can not go further.
Can you see that thinking is not the total field?
Senses see, touch, listen and so on, breathing in and out is going on, there is memory and imagination and thoughts arising in the mind. Anger, fear, anxiety, happiness are the expressions of Life to keep the mind alive. This is the format of Life. Can one see that there is nothing beyond this?
There is the field of senses (touching, seeing and so on)-bound by time and space and the field of memory and imagination, thinking-fluid, not bound. The field of senses is being renewed every moment. This is total field -the field of senses and the field of memory and imagination.
The friction between this moment and the next gives momentum to life. The friction is unending. When you are relaxed in this moment, whatever be the situation, the image for the next moment (comfortable to you) is automatically created. This is the natural momentum on which brain works. When you are not at rest with this moment, you are trying to fix the next moment to your pattern of satisfaction. You miss the automation. You become busy in fighting an illusory battle.
Then what about ideas about God and so on?
You may name the total field as God but the total field is not an object or something, you can refer. You can not separate yourself from the total field and discuss about the total field. You and the world is a singular process, is the total field.
What ever comes before you including stars, galaxies and so on can not be the source. It is an object. It can have some use, function. To come to the source, the subject (you) is also to be included. To see that subject-object is a singular process rests all seeking.
