## Introduction
It has been clarified in the preface that purification of the soul can only be achieved through the study of scriptures. These scriptures are divided into four sections - Charan Karananuyog, Dharmanuyog, Ganitanuyog and Dravyanuyog. The Charan Karananuyog is described in the Kalik Shruti etc., the Dharmanuyog is described in the Rishi-Bhashit etc. sutras, the Ganitanuyog is described in the Surya-Pragyapti etc. sutras and the Dravyanuyog is fully described in the Drishti-Vadang. In addition, some information about Dravyanuyog is also found in the Ang or Upang etc. sutras.
Here, we need to specifically discuss the Charan Karananuyog, as our present scripture 'Dasha Shruta Skandha Sutra' is particularly related to it.
Before we discuss the present text, it seems necessary to say something about 'Shruta Adhyayan'. We have already said that 'Shruti' is the name of religious scriptures. The texts that describe principles, teachings and conduct are called religious scriptures or Shruti. From a practical perspective, conduct should be given the first place. Because, how can the mind of a person whose conduct is not pure be focused on the subject of principles? Teaching seems impossible for him. Because only the person whose conduct is pure has an impact on the people. If a drunkard advises others not to drink alcohol, the listeners will look at him with disgust instead of respect. But the person whose conduct is pure, even without saying anything, people will serve and worship him.
