I began meditating a couple years ago, with the help of guided mediation CD's and crystals. Everything in our universe is created out of vibrating energy, matter is just energy condensed to a very slow vibration. (I have a cool theory about the shapes these standing waves could take, ask if youre interested). Crystals carry a high vibration, and have different effects on you bodies own vibe. Amythest is a great crystal to meditate with at first, it helps to open you 3rd eye. The Chakra system is the idea that we have 7 major spinning energetic vortexes within our physical body (and more!). These Chakras correspond physically with your endocrine system, or your hormonal glands. By meditating and becoming aware of the energetic flow within your body, you can balance your chakras and balance your hormones. In deep states of mediation (focused awareness), your brain releases feel good chemicals such as serotonin and dopamine. I also think it may release small amounts of DMT in meditation.
Take from this that which resonates with you. I believe in this 'crazy' stuff because it helps makes me a happy, loving, balanced person. Its cool to think that there is a divine spark of Creator within each of us. We are here to explore this world of polarity and duality, and to realize that we are all Creators. We are all creating our own reality, and together we shape our world. Let's choose to make it awesome! But there are many paths you can choose to walk, and only YOU will know whats right for you. I could go on about this shit for a while, but its bed time for nowEndFragment
