Tamāla Kṛṣṇa: Purport: "In the previous chapter, as a prelude to the Bhagavad-gītā, many different paths were explained, namely sāṅkhya-yoga, buddhi-yoga, controlling the senses by intelligence, work without fruitive desire, the position of the neophyte, etc. This was all presented unsystematically. A more organized outline of the path would be necessary for action and understanding. Arjuna therefore wanted to clear up these apparently confusing matters so that any common man could accept them without misinterpretation. Although Kṛṣṇa had no intention of confusing Arjuna by any jugglery of words, Arjuna could not follow the process of Kṛṣṇa consciousness either by inertia or active service. In other words, by his questions he is clearing the path of Kṛṣṇa consciousness for all students who are serious about understanding the mystery of the Bhagavad-gītā."
Prabhupāda: Yes. Sometimes it appears to the student contradictory. But actually, the master who is well conversant, he does not say anything contradictory. It is the misunderstanding of the student that sometimes he thinks that it is contradictory. Therefore the question is allowed. You'll find that a student is advised to question to the spiritual master. Tad viddhi. You should understand the transcendental science by the process of... First thing is surrender; then question, and sevā, service. Surrender and service and question. Simply if you question, and don't surrender, don't render any service, then it will be simply waste of time.
Just like Arjuna was talking in the beginning with Kṛṣṇa as friends. So Kṛṣṇa was talking very cautiously because it was friendly talk. But when Arjuna surrendered unto Him, "I accept You as my spiritual master," He's talking freely. This is going on. Go on.
Tamāla Kṛṣṇa: Three: "The blessed Lord said, 'O sinless Arjuna, I have already explained that there are two classes of men who realize the self. The contemplative are inclined to understand it by empirical philosophical speculations, and the active are inclined to know it by devotional service (BG 3.3).' "
