Each form of life supports all others; together they weave the grand web of life. Thus there really is no happiness for oneself alone, no suffering that afflicts only others.
Material possessions cannot be enjoyed after death. But millionaires rich in life force are able to freely make use of the treasures of the universe in lifetime after lifetime and enjoy a journey of eternal happiness. That is what constitutes proof of true victory in life.
The real struggle of the 21st century will not be between civilizations, nor between religions. It will be between violence and nonviolence. It will be between barbarity and civilization in the truest sense of the word.
