The truth is that you cannot attain God if you have even a trace of desire. Subtle is the way of dharma. If you are trying to thread a needle, you will not succeed if the thread has even a slight fiber sticking out.
It is true that God is even in the tiger, but we must not go and face the animal. So it is true that God dwells even in the most wicked, but it is not meet that we should associate with the wicked.
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.
A man develops a subtle power as a result of the strict observance of celibacy for twelve years. Then he can understand and grasp very subtle things which otherwise elude his intellect. Through that understanding the aspirant can have direct vision of God. That pure understanding alone enables him to realize Truth.
The way of love is as true as the way of knowledge. All paths ultimately lead to the same Truth. But as long as God keeps the feeling of ego in us, it is easier to follow the path of love.
So long as one does not become simple like a child, one does not get divine illumination. Forget all the worldly knowledge that thou hast acquired and become as a child, and then will thou get the divine wisdom.
A truly religious man should think that other religions also have many paths leading to the truth.
One should always maintain an attitude of respect towards other religions. Dispute not, as you rest firmly on your own faith and opinion, allow others also equal liberty to stand by their own faith and opinion.
We laugh at the efforts of the musk deer to find the source of the scent which comes from itself and despair at our efforts to find the peace which is our essence.
