"A person who makes his happiness dependent on material or physical pleasures will never be guaranteed happiness. There is always something that might happen to destroy his happiness and success. The only guarantee for happiness is to find happiness in spiritual growth."
"A person who appreciates that the Almighty created everything in the world for his benefit is aware of the multitude of good things he has in the world. With this appreciation, no one considers himself poor in comparison to anyone else just because the other person has a little more than him. Even the poorest person in the world has many things for which to be thankful. Everyone has the ability to be in a state of happiness. Do not allow another person’s having more than you rob you of your happiness."
"What is the difference between mourning and sadness? Mourning takes hold of one’s heart, but not one’s mind, while sadness takes hold of the mind. Mourning leads to thinking, while sadness stops one’s thoughts. Mourning stems from the light in one’s soul, while sadness comes from the darkness of the soul. Mourning arouses one to life, while sadness brings to the opposite. The Torah obligates mourning when it is appropriate, while it forbids sadness and commands we serve the Almighty with joy."
