Raja-Vidya: The King of Knowledge is a penetrating exposition of the Ninth Chapter of the Bhagavad‑Gītā — which begins with the verse: “rāja-vidyā rāja-guhyam pavitram idam uttamam…” (BG 9.2).

In this compact work, Srila Prabhupāda reveals that the “king” of all knowledge is not academic learning or worldly skill but the knowledge of the Supreme Person, the Lord, oneself, and the eternal nature of reality.

Key themes include:

• The nature of true knowledge (“vidyā”) and why it is called “raja” (king) — because it governs all other forms of knowledge and leads to liberation.

• How knowledge of the Supreme transcends the cycle of birth and death (saṁsāra) and brings about lasting peace and fulfilment.

• The energies of the Lord, the importance of great souls (mahātmās) as witnesses to this knowledge, the disciplic succession (paramparā), the Lord’s pastimes and forms, the role of faith in guru and surrender to the Lord, and how to act in this knowledge. 

Presented in readable and accessible language, this edition is ideal for seekers of spiritual truth, students of Vedic wisdom and anyone wanting to elevate their vision from material understanding to divine insight.
