There is no one there. In fact, everything we engage in is conceptualization. The process of meditation helps us realize the truth of the dharma. When we take refuge in the dharma, we are not following some prescribed path. We really have to look inside our own mind, and the dharma helps us to do that.
Truth is constant, so the dharma provides some stability in our life.
Finally, we take refuge in the sangha, the people who are on the path with us. Those who are in the sangha are warriors, because they are trying to overcome samsara. Members of the sangha support one another and care for one another. They are not perfect, but they inspire us because they are people who want to deepen their practice of mindfulness, awareness and compassion. The sangha is also a container.
