It is an authentic holistic tradition inclusive of contemplation & meditation. Its aim is for you to achieve your fullest potential in life, since you possess a storehouse of immense happiness within you! It's not essential to be young & supple to practice Yoga & Meditation... all that is needed, is a desire to be happy."
