Near the chapter's close, Krishna makes a sweeping declaration. The yogi stands above three other types of seekers. Above the tapasvi — the ascetic who endures physical hardship. Above the jnani — the scholar who masters texts. Above the karmi — the ritualist who performs ceremonies. The yogi, who integrates all three through inner discipline, surpasses them all.
This is not meant as a ranking that diminishes the other paths. Tapas, jnana, and karma are all valuable. But each alone is partial. The ascetic may mortify the body without touching the mind. The scholar may know every text without transforming the heart. The ritualist may perform every ceremony without inner stillness. The yogi brings body, mind, and action together.
And then the direct call: 'Tasmad yogi bhav Arjuna.' Therefore, be a yogi, Arjuna. Not 'think about it.' Not 'consider it.' Be one. It is one of the clearest instructions Krishna gives.
