It is a Buddhist belief that before we were born into these physical, temporary shell bodies, we were once a part of the vast ocean in the universe. We were a drop in that ocean of comfort, warmth, truth, and unlimited wealth of knowledge. Now, in these bodies, we strive for enlightenment (at least many spiritual people do), or at least a better understanding of everything, and we meditate and meditate and contemplate the workings of people and the universe, we contemplate everything, just to be awakened to the bigger picture. We meditate to be enlightened or awakened...that enlightenment that the Buddha and the Dalai Lama and many other masters like Vernon Kitabu Turner and O Sensei Morehei Ueshiba (the founder of Aikido) have acquired is that original, unadulterated wealth of knowledge we used to have, before we left that ocean, before Adam and Eve ate from that fruit....we meditate to once again be apart of that mind, to find that truth of the universe! We meditate to be awakened to that state we were supposed to be in. When Adam and Eve bit from the fruit, and once we grow to a reasonable age, they (and we) analyze(d) things, think of everything and try to solve everything and piece together everything through Logic, through Reasoning, but we were never supposed to in the first place. Because in the universe, in our vast ocean of warmth, comfort, truth.....there was no need for reasoning and logic; it just WAS. JUST LIKE what Buddhism TEACHES: IT JUST IS!
We started rationalizing in the first place because when many of us reach a certain age, we get curious about everything; we start researching, conversing with people, traveling, reading, watching, learning ALL we can to better understand this world and our purpose for existing. It's like something or someone WANTS us to learn, see how far we can get on our own. Why would we all be here on earth if we were all happy and content and comfortable and knew the truth already? Why would earth and humans and animals exist? What IS our purpose? Some may say it's to be tested in this life, and that may be true. Or it can be something deeper. It's up to you to interpret.
"Life isn't about finding yourself; it's about creating yourself."
