यो मामेवमसंमूढो जानाति पुरुषोत्तमम्।
स सर्वविद्भजति मां सर्वभावेन भारत।। १५.१९ ।।
Summary Translation:
Whoever knows Me as the Supreme Personality of Godhead, without doubting, is to be understood as the knower of everything, and he therefore engages himself in full devotional service, O son of Bharata.
In this nineteenth verse, Shri Krishna explains the transformative power of knowing Him as the Supreme Person. He states that anyone who is undeluded (asammūḍhaḥ) and knows Him as the Purushottama becomes all-knowing (sarva-vit) and worships Him with his whole being (sarva-bhāvena). This analysis defines the highest form of wisdom. To be undeluded means to have cleared away the misconceptions that God is merely a human being, a myth, or a limited energy. When a seeker realizes Krishna's supreme position, they don't just gain a piece of information; they gain the Key to all Knowledge. If you know the root of the tree, you automatically know the leaves and branches. Similarly, by knowing the source of all existence, one understands the underlying principles of the entire universe. This knowledge naturally leads to total devotion, where the seeker's mind, heart, and actions are all directed toward the Divine.
From a religious standpoint, this verse emphasizes Total Commitment. The phrase Sarva-bhāvena is deeply significant; it means with every fiber of one's being or in every mood and situation. It suggests that true devotion is not a part-time activity but a state of consciousness. This detailed analysis shows that Knowing and Worshipping are not two separate things but two sides of the same coin. Deep knowledge leads to deep love, and deep love leads to deeper knowledge. For the devotee, this verse is a Certification of Spiritual Maturity. It tells us that the goal of all Vedic study is to reach this simple yet profound conclusion: Krishna is the Supreme Person. This realization simplifies the spiritual life. Instead of being distracted by thousands of different practices, the all-knowing devotee focuses purely on loving service. This verse provides Arjuna with the Final Clarity he needs. It promises that by choosing Krishna, he is choosing the highest truth, which will guide him through the complexities of his duty with a heart full of devotion and an intellect full of light.
The philosophical weight of Shloka 19 lies in the Theory of Holistic Epistemology. , it posits that Knowledge of the Whole is superior to Knowledge of the Parts. This addresses the Synthesis of Wisdom. In this religious theory, the Purushottama is the Integrative Principle of the universe. , being undeluded means achieving the Aparoksha Jnana—direct, non-mediated perception of the Divine. Philosophically, this suggests that the ultimate truth is not discovered by an Accumulation of Facts but by an Orientation toward the Source. The term Sarva-vit (all-knowing) implies that once the source is known, there is nothing else of essential value left to be known.
The significance of Sarva-bhāvena provides the framework for Integral Devotion. , it means that the devotee’s Bhakti is not limited by a specific path but encompasses all states of mind—joy, sorrow, action, and rest. Philosophically, it addresses the Unity of Life. This verse bridges the gap between the Intellect (knowing) and the Heart (worshiping). It suggests that a Fragmented Person can only worship fragmentarily, but the Whole Person (who knows the Whole God) worships with Whole Being. This leads to the theory of Ananya-Bhakti—exclusive, one-pointed devotion. The goal is the Total Alignment of the individual will with the Divine Will. This analysis provides the justification for why the 15th chapter is called the Science of the Supreme Person. It is a science because it provides a predictable result: whoever knows the Purushottama becomes all-knowing and all-devoted. It represents the ultimate Convergence of all spiritual disciplines into the single, simple act of surrendering to the Supreme Person with full understanding.
