In this life, we can light the lamp of peace. We can decorate the heart with the lamp of peace every day. Learn how to light that lamp. You can call to that peace, that joy, so that it comes to you. All those corners where there is darkness can be filled with joy. Joy doesn't look at anyone's age, whether they are young or old. No matter what their condition, it is possible for every human being to feel joy. If you need to make an effort, then the effort should be to light the lamp of joy. This life should be filled with light, not darkness.
