Swami Vivekananda, (1863-1902)
We believe that every being is divine, is God. Every soul is a sun covered over with clouds of ignorance; the
difference between soul and soul is owing to the difference in density of these layers of clouds.
“Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain,
muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the
way to success, that is way great spiritual giants are produced.”
“We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make
ourselves. If what we are now has been the result of our own past actions, it certainly follows that whatever we
wish to be in future can be produced by our present actions; so we have to know how to act.”
“Never think there is anything impossible for the soul. It is the greatest heresy to think so. If there is sin, this is
the only sin ? to say that you are weak, or others are weak.”
“You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other
teacher but your own soul.”
“We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts
live; they travel far.”
There are three ingredients in the good life: learning, earning and yearning."
- Christopher Morley
“Success is simple. Do what's right, the right way, at the right time.”
Arnold H. Glasgow
"Success is a journey, not a destination."
Ben Sweetland
“Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will
be successful.”
Herman Cain quotes
"Success is not permanent. The same is also true of failure.”
Dell Crossword
When you know what you want,and you want it badly enough,you'll find a way to get it .
Jim Rohn
"Meet success like a gentleman and disaster like a man."
Frederick Edwin Smith, Lord Birkenhead
