“Only an instant does this world endure.”
The images you see in the world will pass. They will pass one after the other as you gradually develop the skill in staying your focus on the good and the lovely, in you and in whatever you meet.
Love, joy and peace are what everything is made of and they last throughout time and beyond it. Distress, sadness and depression are states of mind that are seemingly justified by the images in the world they have conjured up.
When more and more you fill your mind with the good and the lovely, those sad images will cease to come to you. They will vanish as will time in which they appeared.
