Practicing Buddhism does not have to grasp to forms which is the performance of discrimination(vikalpa). Practice Pure Land is the same as it. What is called the Pure Land is not that there is another matter world of Pure Land out of the universe. It is not so. The Pure Land is in our hearts. The pure heart is just the Pure Land. The Buddha-fruit and Buddha field that we devise are all in our minds. "The myriad dharmas are made from the mind alone. " We usually says the dignity of the Pure Land is not that there is a place like the garden needing us to water flowers and plant trees, but that we must purify our own minds. Each one around the world has a pure mind, which is just the Pure Land. (From Words of Chan by Shi Yongxin)
