Conclusion

Driven by compassion, the Buddha expounded his teaching 
without keeping back what was required for man’s deliverance from Samsara.

Perfect enlightenment 
is not the prerogative of a single chosen being by a mighty God. 
It is an achievement open to anyone 
who earnestly strives for purity and wisdom.

        “By oneself is evil done;
        By oneself is one defiled;
        By oneself is evil left undone;
        By oneself is one purified;
        Purity and impurity depend on oneself
        No one can purify another”
Do not believe any being can give you instantaneous Nibbana. 
The Buddha, Dhamma and Sangha is your constant guide in your strive to Nibbana.
