Difference is not an evil, it is a blessing. Difference creates intellectual challenge. It activates the mind. It accelerates the process of thinking. Thus difference leads to intellectual development.
Life is full of differences. There is no escape from it in a human society. So we have to live with differences rather than try to eliminate them. Coexistence is the only way of peaceful existence.
There are two sides of the human personality — the material side and the spiritual side. If man feeds only the material side of his personality, he will always suffer from feelings of deprivation. But if he feeds the spiritual side of his personality along with the material side, he will not suffer from such feelings of deprivation.
Happiness is a state of mind. It does not exist outside of it. One should learn this principle, and only then will one see things in a different manner. Only you can make yourself happy. No one can gift happiness to you.
