Focus on the different muscles of the body alternately and feel them deeper and achieve the relaxation.
We always use more energy than is necessary, by using unnecessary muscles, by allowing thoughts to revolve and reacting too much with feelings. Relax muscles, use only those necessary, store thoughts and don't express feelings unless you wish. Don't be affected by externals as they are harmless in themselves; we allow ourselves to be hurt.
