What is meditation? Meditation is the power which enables us to resist all this. Nature may call us, "Look there is a beautiful thing!" I do not look. Now she says, "There is a beautiful smell; smell it! " I say to my nose, "Do not smell it", and the nose doesn't. "Eyes, do not see!" Nature does such an awful thing - kills one of my children, and says, "Now, rascal, sit down and weep! Go to the depths!" I say, "I don't have to." I jump up. I must be free. Try it sometimes. ... [In meditation], for a moment, you can change this nature. Now, if you had that power in yourself, would not that be heaven, freedom? That is the power of meditation.
