All around us is "evidence" that life happens in a material world, a cause and effect world where we rely on outside/material sources for everything.
Don't be fooled!
You can do SO much psychically, and the better you understand the nature of reality, the more you rely on inner sources, the more you can manage and maintain psychically.
Have the intention for the highest possible standard in everything. Know that at the core is energy. That's where it all starts. It is first. Matter comes second. So everything depends on that original thought, that original intention, main belief.
If you know that we create from thought, in cooperation with all of life, and that the universe is always cheering for out highest well being and most creative expression, then ally with the Truth and the Highest forces to create beauty, love, harmony, joy -- the highest qualities; the eternal qualities.
