You get what you concentrate upon. There is no other main rule.
Your desire or beliefs will literally be reaching back into time, teaching the nerves new tricks. Definite reorganizations in that past will occur in your present, allowing you to behave in entirely new fashions. Learned behavior therefore alters not only present and future but also past conduct.Jane Roberts
The Point of Power Is in the Present.Jane Roberts
In terms of earthly life as you understand it, it is overly optimistic to imagine that eventually all illnesses will be conquered, all relationships be inevitably fulfilling, or to foresee a future in which all people on earth are treated with equality and respect.Jane Roberts
