Peacefulness is an inner sense of calm - it comes from becoming still - in order to reflect and meditate on our inner wisdom and receive answers. A peaceful heart is one that is free from worry and rouble. It's becoming quiet so we can look at things quietly so we can more clearly understand them and thus come up with creative solutions. It is learning to live in the present. Freedom from desire leads to inner peace.
Don't think you can attain total awareness and whole enlightenment without proper discipline and practice. This is egomania. Appropriate rituals channel your emotions and life energy toward the light. Without the discipline to practice them, you will tumble constantly backward into darkness.
Intellectual knowledge exists in and of the brain. Because the brain is part of the body, which must one day expire, this collection of facts, however large and impressive, will expire as well. {But spiritual insight transcends death.}
Prepare for the difficult while it is still easy. Deal with the big while it is still small. Difficult undertakings have always started with what easy. Great undertakings always started with what is small. Therefore the sage never strives for the great,And thereby the great is achieved.
