I am certain that there is no singular meaning of life that applies equally to everyone. There is a great parable of the six great Jewish prophets which supports my view:

• In answer to the question: ‘where is truth?’, the meaning of life, the first Prophet, Moses, ‘who had revealed’ the one God to the people, pointed a finger up towards the sky;
• the second prophet, Solomon, who was known for his great wisdom, pointed a finger to his head;
• the third prophet, Jesus Christ, who had called the world to compassion placed his hand on his heart;
• the fourth prophet, Karl Marx, who led the class struggle and the battle for survival, stroked his stomach;
• the fifth prophet, Sigmund Freud, with his basic instinct pointed, naturally, a little lower.
• Then came the sixth prophet, Albert Einstein, who declared that the answer to the question was relative and depended on a system of coordinates specific to the person concerned.

The parable above (author remains unknown) was quoted in the third part of “The Last Faith: a book by an atheist believer”.
