Nana folded his hands and prayed, 'Baba, I have some difficulty in
understanding, here. You said the Bramhan is devoid of pain and it envelopes
everything. It is blissful too. My Mother, you said everything contains this
Bramhan. I, however, find that the world is full of miseries and pain. It is
also infinite. I do not see any properties of Chaitanya in it. How can a
born-blind see beauty? How can Real Chaitanya live in an illusory thing? If
the Soul itself is the life force, then its unity does not exist at all
because there are many souls. The pleasure and pain of one soul do not
affect others. How can we? Then say that all of them contain the same
Chaitanya? Since the bodies are different I feel that the souls are also
different."

Baba said, Nana,you make a mistake, here. Now listen to me with full
concentration. If we mix red, white, black, yellow, blue, green, violet and
crimson colours separately with water and keep these mixtures in different
glasses, can the water be different? It gets red colour with red and yellow
with yellow. If we separate the colour from the mixture, the colour of the
water will not be visible again. In the same manner, after the union of the
soul with heart, experience of miseries and pain are caused. Bodies of the
animals are different but there is no difference in their souls. All of them
have the same soul. Pleasure and pain are the properties of the heart
(body). The body, however, is necessary for the soul. Understand this, My
Child.

Now, I will analyze this topic so that you will understand it well. My
child Narayan, the Chaitanya has three qualities. They are spiritual
(Parmarthic), customary (Vyavaharic) and illusory (pratibhasic). They are
similar to the three states of the body viz. childhood, youth and old age.
The souls who have reached the state of spiritualism are considered as
holymen. Those who understand the difference between the right and the wrong
and follow" the Shastras are called customary. Those who consider illusion
as the truth are called illusory. They are covered with nescience, Nana.
