It is said of the Diamond Way that the best practitioner can reach enlightenment within one single lifetime. This is extremely fast, especially when it is compared to the Sutra approach where enlightenment can be obtained only within aeons. But not every practitioner is able to use such powerful methods. Most traditions in the Mahayana are based on the Sutra approach. Only Tibetan Buddhism uses and transmits all the Tantric methods that the Buddha has given.
Enlightenment expresses itself in different forms.
All the Buddhas of the ten directions and also the high Bodhisattvas manifest a pure powerfield around themselves, which is their own pure land. Buddha Shakyamuni described the qualities of these pure lands in detail. He taught different methods to connect with the Buddhas and their pure lands because, compared to other methods, the practice of the pure lands is a relatively easy way to enlightenment. He bears this name, because the light radiating from his body pervades all the pure lands of all the Buddhas of the ten directions. Many aeons ago, in connection with his Bodhisattva promise, he made extremely strong wishes that he would be able to manifest a pure land which combines the qualities of all other pure lands, and that all beings who made corresponding wishes would be reborn there easily.
