Now, we all talk about permanent spiritual enlightenment. But, if Lord Buddha could not find and teach the path, we will only blindly follow science as thinking permanent enlightenment is not possible. I am not talking about spirituality, moral virtue or temporary blocking  defilement  with higher meditation Jhana levels. I am talking about permanent enlightenment (Nirvana). Even if we practice moral virtue for a long time without knowing ‘Three Marks of Existence’ and ‘Four Noble Truths’ it will just only a temporary higher moral virtue.Lord Buddha shows that, there are nine beyond world things('Nine supermundane things' / Nava-lokuttara-dhamma). So, Permanent enlightenment is possible in four levels since these special kind of mental consciousnesses. Once after any one experience those consciousness he reach enlightenment permanently in some levels.

If any one could experience Magga-citta he will definitely experience Phala-citta in the Chitta stream without any delay. When we do a Karma result come with some delay. But for Magga-citta resultant Phala-citta come instantly. It is said that if any one could experience Magga-citta just moment before the world end, the entire world ending process will delay till he experience the Phala-citta. Magga-citta is so powerful it can stop the world ending for a instant. (Lokuttara Citta: 2 definitions)Magga-citta is the final result of all Threefold Training.

It is known that, at a certain portion of deep places of this river, there are four large gems together on the bottom.
