Kashtha Takshanasana (tree cutters pose) is a dynamic posture which is modeled after the action of a tree cutter.
Manipura chakra, the solar plexus, is the core energetic focus within this posture. With the constriction of the abdominal region and the overall toning of the spinal column isolates the energy of the luminous body towards manipura. Once active, manipura becomes a conduit for creativity and vitality. It is also linked to the visceral organs.
Anatomically this posture loosens the pelvic area including the hips, thighs, and groins. It can therefore be used therapeutically during the first trimester of pregnancy or prior to conception. Stability in this posture is derived from the abdomen, thighs, and lower legs which together are strengthened within this posture. Additional the shoulders and upper back are stretched and strengthened.
Hasta Utthanasana (raised arm pose) is a light posture for enriching the upper body with energy. Introducing the flexion and extension of the cervical spine (neck) motivates the energetic stimulation of vishuddhi chakra, the seat of the intuitive nature of the human being.
Awakening vishuddhi chakra leads towards a superhuman state of consciousness which is liked to the intuitive disposition of human nature. In most people this higher state of being is dormant, suppressed by individualistic thinking and egocentric ideologies. Through this practice you can begin to connect to the energy in and surrounding vishuddhi chakra which will aid in meditation upon the intuitive center.
Physiologically and anatomically this posture helps to correct postural miladies including rounded shoulders and stiffness in the upper back. Moving the arms, head, and breath in a rhythmical cycle increases breath capacity and relaxes the mind. This posture also helps to improve circulation especially to the coronary arteries.
