(THE BEST BOOK ON CHAKRAS, BY A REAL MASTER FOR SURE, ABOVE)The chakras are part of yogic sadhana, and toning up, becoming aware, through poses is a great way to re-create yourself. Most yoga teachers have no clue (including I, though in my favor I can offer that I am curious and wanting to learn:) of these things, and offer quick-fix chakra and kundalini workshops which can really not mean much... because the chakras being out of kilter does not happen overnight. And what has taken your entire life-time of wrong thining and doing (and possibly lifetimes, if you believe in karma) cannot be remedied in a one-off workshop. So this is to open your mind to what you need to do, to clean up, tone up, and make a mint-new you, with your yoga practice. And why you need to strategise all that with sustained practice:)
How do you know which chakra is out of balance. See the list below, if any of the system inside u is constantly snagging, or you have a personality issue then that is how you locate your problem...
Mooladhara -- situated at the base of spine/pelvis. Deals of organs of elimination. Instinct of self-preservation. TO tone up, use STANDING POSES.
Svadhisthana -- tailbone. CREATIVITY, SENSUALITY. Uro-genital system. Tone up with HIP-OPENING POSES.
Manipura -- navel center. POWER. Digestion. Tone u with TWISTS.
Anahata -- heart. LOVE, self love and of others. Breathing, cardio-vascular systems. BACKBENDS.
Vishuddhi- Throat. Communication and listening. Thyroid and upper back/spine. SHOULDERSTANDS AND THOSE THAT WORK THE THROAT.
Sahasrara. Crown center. Pineal gland.Nervous system. MEDITATION, INVERSIONS.
(Each book or author may have something different to say about this. I have loved and lived the book Chakras by Anodea Judith, Ph.D and also been gripped by Harish Johari's book on the same topic. This one, above, list is from the book Myths of the Asanas, by Alanna Kaivalya, Arjuna can der Kooij).
