Nobody is saying that human ideas are necessarily anthropocentric. Ecocentrism is a human idea. However, the beliefs you articulate on this forum, which form the components of what purports to be a grand cosmic narrative, accord central importance to human life. This is by definition anthropocentric. It’s what the word means.
Even if all life has consciousness the fact remains that you effectively believe all non-human life is unable to realise its cosmic purpose and significance until it takes human form. In other words human life is the final end and goal of all spiritual and conscious evolution in the universe as we know it. We are the unique portal through which consciousness might come to know itself as Brahman. Everything leads up to us. Other creatures are in effect little more than lower steps on a stairway whose destination is humanity. No other being has our special significance in this drama. It’s all really about us.
Your story is certainly more inclusive than the narratives found in Abrahamic religions but not really any less anthropocentric. Why should herons and hedgehogs, for example, be mere stepping stones on a journey to us? That would make them just a means to an end. Of course, for you we are also a means to an end but a much more significant one because the cosmic purpose is never realised in herons and hedgehogs.
Humans engage in spirituality because we have a high degree of self-consciousness, but it is this identification with self that causes us the psychological problems we seek to alleviate by spiritual practice. In other words we are (probably) uniquely ‘disabled’ by our cognitive complexity. Looked at from that perspective our specialness seems less attractive. Your idea of spirituality seems to valorise complexity and seeks progress through advancing knowledge, but maybe what we need is to return to something simpler and more honest. Perhaps, if we can find a little humility, it’s our animal nature that will save us from ourselves.
