" The literal meaning of guru yoga is ‘union with the teacher´s nature’. To blend your mind with the teacher’s mind is the most profound of all practices, and the shortest path of realization. It is the life force of the path and the one practice that includes all others. It was through relying on a spiritual teacher that all the bodhisattvas of the past generated the mind of enlightenment and reached perfection. "
