"According to the Zen tradition, when Shakyamuni Buddha attained enlightenment, he said, 'I, the great earth, and sentient beings simultaneously attained the Way; mountains, rivers, grass, and trees have all become Buddha.' In the Lotus Sutra, there is an expression, 'Ten directions are all within Buddha's land.' The Kanmuryojo-kyo (Sutra of Seeing Infinite Life, one of the three major sutras of Pure Land Buddhism) says, 'The light of the Tathagatha of Infinite Life (Amitabha) embraces all living beings without rejecting any.' We have already been enlightened by Shakyamuni Buddha, and are from the beginning in the hands of Amitabha Buddha, who saves all living beings without exception. This is not a matter of understanding it or not. Whether we know it or not, whether we say I don't believe in Amitabha or not, it is true. It is not a problem. The light of Amitabha embraces all living beings whether we believe it or not.
The reality of life or the 'Life of Buddha' is thus. And yet, all of us think and measure and say, 'I don't believe it.' Don't say such cheeky things! The force which makes us think that our minds are great and makes us say such cheeky things itself wells up from the power of Amitabha or the 'Life of Buddha'. We must deeply understand that whether we think so or not, believe it or not, understand it or not, venerate it or not, accept it or reject it, in whatever conditions, we are living out the formless reality of life prior to its division into dichotomies" - Kosho Uchiyama, Dogen's Genjo Koan, Three Commentaries.
