Meditation is not about how you place your body, but about where you place your awareness.
It is neither about mudras nor asanas, but about just being mindful in the crystal clarity of the present.
One does not need to trek mountains or race motorbikes or jump off cliffs to experience the zest of aliveness in the face of danger. Every moment is an opportunity to be face to face with a hundred manifestations of the creator, if we would open our eyes.
Our awareness is the expression of the supreme / universal awareness. It is the key that unlocks the secrets to the universe and God.
