There are two important things for man; one, the head and the other the heart. All that comes out of the head is worldly. This in Vedantic parlance is called outward quality (Pravritti Lakshana). Eating, writing, reading, moving out, earning and amassing and end in human life are all worldly. These outward qualities are not true. They are like passing clouds. Compassion, mercy, kindness, sacrifices come out of the heart. These are qualities of inward nature (Nivritti Lakshana). One is Pravritti – outward and the other is Nivritti - inward. It is not proper to go by the outward nature. Human life is very valuable. It fosters human values and transforms human life into divine life. Understanding the outward and inward natures is the search for truth. Every word, every song, every look should express this truth. Whatever step you take, whatever you do are connected with this search of truth.

A small example. You have eyes. These eyes see one’s own mother, the children, the wife, the daughter-in-law and also the mother-in-law. The eyes that see are one and the same. What is the search for truth here? Here the search for truth means how you should look at your mother, daughter and wife. Likewise, you have the tongue. The same tongue speaks of truth, falsehood and illusion. Here, what is truth? What is illusion? What is falsehood? Here search for truth means investigating what is the truth and adhering to it. We can also have other sources of evidence based on science and technology today.

There is a tree. Some look at the branches and some at the roots. Some think that the fruits and leaves are important because they grow on the branch. The branches, fruits and the flowers are seen outside but they depend on the roots below. Since ancient times, the philosophers are those who take into consideration the basis, the roots. The one who sees the branches, fruits and flowers is the scientist. Those things that are not known to the scientist are taught by the philosopher; that which is not known to the philosopher is taught by the scientist. The combination of science and philosophy is the search for truth. There cannot be branches without roots. There is no use of the roots without branches. Roots and branches are interdependent; they are inter-related. Likewise, every individual should make an attempt to know the inner and outer natures. They only can man understand the truth and conduct himself along the path of truth. (DTB Vol.1, pp. 2-3)
