We all want to achieve the awareness of our true nature: peace, happiness, bliss but our own mind is the biggest hindrance to achieving this goal.
There are many terms defining our brain: acts like a monkey, restless horses, mind of its own, all pointing out the restless nature of our brain. Anyone who has tried to meditate knows, the mind itself is the biggest obstacle standing between ourselves and this awareness.
By patiently practicing meditation, we can calm that restless mind, letting go of the negative thoughts so we can see clearly, to attain stillness. Anyone can practice yoga, regardless of physical ability, religion or circumstances in life.
