The concept of pure land has been documented as arising because of the intention of a bodhisattava, and the five features of Buddhahood have a role.
Pure lands have been documented as arising due to the intention and aspiration of a bodhisattva such as the case of Amitabha, but other discourse has codified that they are entwined with the theory of the sambhogakaya and are understood to manifest effortlessly and spontaneously due to other activities of a Buddha and the pure qualities and the mysteries of the Three Vajras. The five features of Buddhahood - the attributes of the Sambhogakaya - play a role: perfect teacher, teaching, retinue, place and time.
