You can offer your vibration on purpose. That's what visualization is. That's what imagination is: projecting thought energy on purpose.
Esther HicksThere is no condition that you cannot modify into something more, any more than there is any painting that you can paint and not like and just paint over it again. There are many limiting thoughts in the human environment that make it feel like it is not so, as you have these incurable illnesses, or these unchangeable conditions. But we say, they are only "unchangeable" because you believe that they are.
Esther HicksWhen you become so determined that you want to feel good - you have become as your Inner Being is, in such a pure place of Positive Energy - then that which is 'negative energy' simply can't mix with you. It defies Law. If you are very strong and clear about your positive wanting, and feeling it, then 'bad' things simply cannot get in. Colds can't get in, car accidents can't get in, anything that you are not wanting cannot be your personal experience.
