Chapter 4 – JnanaYoga
na hi jñānena sadṛśaṁ
pavitram iha vidyate
tat svayaṁ yoga-saṁsiddhaḥ

In this world there exists nothing as purifying as jnana(knowledge). One who has matured in yoga(devotion) will enjoy this in the course of time.
There is nothing as pure as self knowledge. How will one achieve this state – By perfecting Karma Yoga(service towards Lord). By doing everything for the Lord, one attains self-knowledge.
By doing everything for Lord, we tend to bypass the influence of our mind and do the right thing at every given situation, without acting/reacting based on our emotions. This reduces the baggage which we have been carrying and prevents future baggage which we might create otherwise. We will be purified in the process and the knowledge which is hidden in us(but covered with layers of impurities(?)) will shine through in due course of time.
