Schrödinger stayed in Dublin until retiring in 1955. He had a lifelong interest in the Vedanta philosophy of Hinduism, which influenced his speculations at the close of "What Is Life?" about the possibility that individual consciousness is only a manifestation of a unitary consciousness pervading the universe. Schrödinger expressed sympathy for the idea of tat tvam asi, stating "you can throw yourself flat on the ground, stretched out upon Mother Earth, with the certain conviction that you are one with her and she with you".
