Have you heard people saying, that while going to sleep tell your pillow, that you want to get up at 4.44? This is speaking to your body. You would be amazed to observe that your body does wake up at 4.44 am. Many a time knowingly or unknowingly you tell yourselves, that " I have to do this and I have to do that. I want this and I want that". This is a vibration that your body is recieving, which does get ready for the event. It is natural that some times you are very enthusiastic to do work, another time you just feel like postponing even the most important task. Meditation can channelise vibrations and create a balance between body and mind. Keep Meditating
