Yoga is about attaining to absolute Balance, piercing Clarity, and an inexhaustible Exuberance. With this, you are immensely fit for life.

Yoga is, quite simply, the science of being in perfect alignment, in absolute harmony, in complete sync with existence.

Changing your attitude is pretense - you cannot keep it up forever. The yogic system is about fundamental transformation - that is what ultimately counts.

Your brain activity, your body chemistry, even your genetic makeup can be changed by practicing yoga.  

If you are established in Yoga, it gives you a sense of union with everything around you that naturally brings Balance and Blissfulness.
