This is the entire spiritual life, Ananda, that is, good friendship, good companionship, good comradeship. When a monk has a good friend, a good companion, a good comrade, it is to be expected that he will develop and cultivate the Noble Eightfold Path.
True religion is a universal and (necessarily) ego-transcending psycho-physical motivation of human beings. However, up to the present stage in human history, only relatively few individuals in any generation have been willing and able to make the gesture that is true religion (or, otherwise, true esotericism). In their great numbers, most people have, up to now, never yet been ready or willing to adapt to the true (and progressive) practical, moral, devotional, Spiritual, and Transcendental Wisdom-culture of right life.
Whenever we encounter the Infinite in man, however imperfectly understood, we treat it with respect. Whether in the synagogue, the mosque, the pagoda, or the wigwam, there is a hideous aspect which we execrate and a sublime aspect which we venerate. So great a subject for spiritual contemplation, such measureless dreaming - the echo of God on the human wall!
You speak of doing good to the world. Is the world such a small thing? And who are you, pray, to do good to the world? First realise God, see Him by means of spiritual discipline. If He imparts power you can do good to others; otherwise not.
Give up all desire for enjoyment in earth or heaven. Control the organs of the senses and control the mind. Bear every misery without even knowing that you are miserable. Think of nothing but spiritual freedom.
I consider myself a spiritual atheist. I certainly believe there are forces bigger than ourselves, and that we should be searching, individually, for meaning in our lives. But I don't believe there's a supreme being, an intelligence that created everything.
You may encounter many defeats, but you must not be defeated. In fact, it may be necessary to encounter the defeats, so you can know who you are, what you can rise from, how you can still come out of it.
