"In order to live skilfully, in harmony with the dynamic Universe, it is essential to accept the reality of change and impermanence. The wise person therefore travels lightly, with a minimum of clutter, maintaining the proverbial 'open mind' in all situations, for he or she knows that tomorrow's reality will not be the same as today's. He or she will also have learnt the divine art of letting go - which means not being attached to people and possessions and situations, but rather, when the time for parting comes, allowing that to happen graciously." The elements of buddhism - John Snelling.
"Humans are just shadows and dust! (Gladiator) It doesn't matter where you are from, you are no different from the person borned on the other side of the world. That's why you have social science classes, to study how humans behave. It's just logic, nothing more or less than a computer." Michael Lim.
"Life in every breath. Great men rised and fell. Does it matter to be one?" The Last Samurai.
"God is jealous of us because we are immortal and every moment of our life is precious." Troy. |
