None of these guarantees that one will experience awakening, but the mystical experience may come to those who try very hard over a very long period of time. The common thread in all of this is an attitude of playful open-mindedness. Awakening is willed. Awakening has no ontological significance. Awakening is not related to morality.
Awakening solves some problems yet causes others.
Awakening is not permanent. In Eastern thought, awakening results in a permanent change such that from then on, the enlightened one dwells in God consciousness. There is no hierarchy of awakened states. But it is likely that those who claim to have experienced ever more advanced mystical states do so in order to recruit and bamboozle followers rather than to aid spiritual understanding. Awakening is less important than is usually thought.
