The chakras are energy centers along the spinal column. When focusing on the chakras, the meditator need not be mentally concerned with exact location. A feel for location develops with practice. The best tool for exploring the chakras is relaxation. Just go to the general place, let go, and simply be. It depends less on ‘doing’ than ‘knowing’, less on ‘knowing’ than ‘feeling’, and less on ‘feeling’ than ‘being’. It can’t be overstated—relax.
