Whenever we want to learn something new, we do one of two things. We either listen to the advice of an expert, or read a book written by an expert. We study their teachings, we put their teachings into practice. Slowly, we begin to understand what they are talking about, and someday, become an expert ourselves. All this becomes possible only when we have faith in the teacher, and when we diligently follow their instructions. The forum in which we obtain knowledge through contact with knowers of that which is the ultimate reality, the "sanga" with the "sat", is known as "satsanga".
 
Shri Krishna says that if we are not qualified to follow any of the techniques mentioned in the previous shloka - dhyaana, saankhya or karma yoga - we need not worry. We can obtain the same result of those techniques if we find a competent guru and diligently follow the path prescribed by them. Just hearing the teaching is not enough. If the doctor gives you a list of foods to avoid eating, you will not improve your health unless you follow their instructions. Similarly, we must become “shruti paraayanaha”, uphold the teachings as the ultimate goal of our lives. Satsanga should become an integral part of our lives.
 
So then, what is the result of those who follow this path? They will be able to overcome death, in other words, they will achieve liberation. Death does not just refer to the loss of the physical body. Every time we get fascinated by the material world and rush to act with selfish desires, we forget our true nature and take on the role of a doer, an experiencer, a meritorious actor or “puntyaatmaa” or a sinner. Each time we forget our true nature as the blissful eternal essence to rush out into the world and eventually experience sorrow, we “die” as it were. So therefore, Shri Krishna says that one who simply follows the instructions of their guru diligently will overcome death.
 
In these two shlokas, Shri Krishna covered the types of spiritual techniques required to access the Purusha within. He now begins a new topic in the next shloka.
