The human body serves as an antenna for the waves of energy and information in which you at all times are swimming. This is why you want to keep the spine straight while in meditation. But understand that you are not just a receiver of energetic information, but a transmitter as well. Every thought you think goes out from you, radiating into the universe and having an effect on all that wave of energy touches. Think how you can affect your world by consciously creating your thoughts and deliberately focusing them when you wish to see a desired result.
Be a conscious creator, not an unfocused transceiver. If you are not happy with the circumstances in your life, this is an indicator that your thoughts are out of alignment with your desires. Stand tall, ask for and receive guidance through your internal antenna, then send out to the universe thoughts and visions of that which you wish to see in your life. It is not magic. Things do not happen by themselves. You are a co-creator of the universe. Do so responsibly and always with love.
