“Arjuna said: O Keshava, I wish to know about Prakriti and Purusha, the Field and the Knower of the Field, knowledge and the object of knowledge.”
Chapter 13 opens with Arjuna's question covering three fundamental pairs: Prakriti/Purusha (matter and consciousness), Kshetra/Kshetrajna (the field and its knower), and Jnana/Jneya (knowledge and the knowable). These are not separate questions but three ways of asking the same deepest question: what am I, and what is the world? The entire Vedantic tradition rests on correctly answering this question.
This question is the beginning of Jnana Yoga — the path of discriminative inquiry. Ask yourself: 'Am I the body that experiences, or the awareness that witnesses the body experiencing?' This simple question, held sincerely, is the entry point into the deepest spiritual inquiry.
