Srimad Bhagavadgita Sadhaka Sanjivani -Swami Ramsukhdas
A man, should perform action and also know the art of their performance. He cannot perform actions properly and scrupulously, without either of the two. Therefore, in the third chapter, the Lord has laid special emphasis on the performance of actions, but has also said, that a striver should know what action is; in the fourth chapter He has laid special emphasis on the knowledge of the true nature of action, and also mentioned the necessity of performing action. In the fifth chapter, the Lord has described both the paths of Knowledge (Sankhyayoga) and of Action (Karmayoga), as means of God-realization, yet He has declared, that the path of Action is superior, to that of Knowledge. In this chapter, the Lord having systematically described the paths of Action and Knowledge, in answer to Arjuna's question has dealt with the path of meditation, in brief and of his own accord described the path of Devotion, in the last thereby expressing his aim that every striver should follow this path which is the best of all.
