It’s being said loudly and often by teachers of my generation that modern yoga has become too superficial. In an article in the American Yoga Journal, Ann Cushman makes the case for the importance of asana practice. But then, she then goes on to say that when students become more serious about practicing, they need to take on some of the other instruments in the yogic toolkit.
Thank goodness yoga is for all ages: the baby in utero, her mother and her grandmother, as well as kids in school and older kids in grad school. Sportsmen, mechanics, and musicians do yoga along with retirees and renunciates.
At every age and stage, we know yoga to be a stretchy system that bends to your needs. Not only that, it helps foster well-being, sweetens your nature and confers long life. Perhaps it will give enough detachment so that as you advance in age, you will be merely amused by any belittlers.
