As the shell, the pith and the kernel of the fruit are all produced form one parent seed of the tree, so from the one Lord is produced the whole of creation, animate and inanimate, spiritual and material.
Spirituality automatically leads to humility. When a flower develops into a fruit, the petals drop off on its own. When one becomes spiritual, the ego vanishes gradually on its own. A tree laden with fruits always bends low. Humility is a sign of greatness.
There are three kinds of love;
unselfish, mutual, and selfish.
The unselfish love is of the highest kind;
The lover only minds the welfare of the beloved and does not care for his own sufferings.
In mutual love the lover not only wants the happiness of his beloved;
but has an eye towards his own happiness also. It is middling.
The selfish love is the lowest. It only looks towards its own happiness,
no matter whether the beloved suffers weal or woe.
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.
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.
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.
Meditate upon the Knowledge and Bliss Eternal , and you will also have bliss. The Bliss indeed is eternal, only it is covered and obscured by ignorance. The less your attachment is towards the senses, the more will be your love towards God .
With sincerity and earnestness one can realize God through all religions. The Vaishnavas will realize God, and so will the Saktas, the Vedantists, and the Brahmos. The Mussalmans and Christians will realize Him too. All will certainly realize God if they are earnest and sincere.
