Explain pure land or Zen Buddhism

Pure Land Buddhism   is   Amitabha Buddha  means "Infinite Life" and  is the name of the Buddha who created and resides in Sukhavati, the Western Paradise of Eternal Bliss (also known as the Pure Land). In his great compassion Amitabha Buddha vowed that any beings who wish to be reborn here will have their wish fulfilled with his help.

The essential practice in Pure Land Buddhism is the chanting of the name of Amitabha Buddha with total concentration, trusting that one will be reborn in the Pure Land, a place where it is much easier for a being to work towards enlightenment. Pure Land Buddhism adds mystical elements to the basic Buddhist teachings which make those teachings easier to work with. These elements include faith and trust and a personal relationship with Amitabha Buddha, who is regarded by Pure Land Buddhists as a sort of savior; and belief in the Pure Land, a place which provides a stepping stone towards enlightenment and liberation.  Pure Land Buddhism is particularly popular in China and Japan.
