HOW TO MEDITATE
When you meditate, take up the position which is most comfortable for you. You do not have to go into physical contortions. Rest and relax. Tell yourself to relax and release all your limbs, including your head, neck, face, into a state of utter limpness.
I must impress on you that meditation should be - eventually - as simple as slipping into slumber. The purpose of meditation is to enable your entire consciousness to move beyond the boundaries of intellect and reason. There are teachers who will tell you to 'imagine' ... whatever you are told to imagine, you can rest assured you are not being assisted to go anywhere except into new imaginative realms of your own thought processes.
