Does the "Grizzly Man" show any sign of religion?

For the odd yet sentimental film that it is, I do think the Grizzly Man conveys some form of religion in what he does. For this specific blog, I am going to define religion as a belief or practice that does something emotionally for people. With this definition I am assuming that people do not practice in order to gain physical incentives.
Every summer for fourteen years the Grizzly Man faithfully traveled to Alaska and spent months living among the grizzlies. He did not do this for money or recognition. He only did it because he felt a strong connection to the grizzlies. This ties to my definition of religion because the Grizzly Man did not perform his "ritual" every summer to gain physical incentives; what he did was purely on an emotional level.
Alaska was his sacred place. When he was there it seems as if he was at peace. This is the same sort of feeling religion evokes from people. Even though certain rituals may look absurd to the human eye, we perform them becaues they allow us to create a sacred place for ourselves on Earth.
We may think the Grizzly Man's documentary on grizzlies to be odd and dangerous but his interaction with the grizzlies is a ritual for him because he "performs" it faithfully every summer for a few months. He does not perform the ritual to gain physical incentives such as money or fame but instead performs the ritual to create a sacred space for him on earth.
