One should understand the need for being in touch with sages and seers in the context of one's own spiritual progress. Unless one understands one's own character there can be no spiritual progress. In one's normal consitutional position, Maya covers the intellect, making it difficult to perform self-analysis. Under these circumstances consulting with a sage can be of highest merit.
A Sage, is one who is the epitome of Truth. Unless one becomes capable of recognizing a sage, it shall be difficult to discriminate between what is true and what is a lie. A Sage is a personfied representation of the Vedic Scriptures. If one is able to get the association of a true sage, understanding the scriptures shall be simplified. One has to first be able to read the symptoms of a sage.
Sages are the pivot that hold people together. They are the source which ignite the spiritual fire amongst the population. Without sages the spiritual landscape of any region shall be barren. Without them, life would not have that extra dimension, the dimension of the spirit. Unless one is blessed by a sage, it is verily not possible to succeed in spiritual life.
