You'll find in the Fifteenth Chapter. The Lord says, vedais ca sarvair aham eva vedyo [Bg. 15.15]. The purpose of all scriptures and Vedas is to know Krsna or God. And the Upanisad says, kasmin tu bhagavo vijnate sarvam idam vijnatam bhavati. If you simply understand the Supreme Absolute, then you understand everything. So this Krsna consciousness means it includes everything. The karmas' activities, fruitive actions, the jnanas', philosophers' speculation, the yogis' mystic power, and bhaktas', devotees' worship of the Lord - everything is included. Just like if you have got a millions of dollar, then ten dollar is there, five dollar is there, twenty dollar is there, everything is there. So if you take to Krsna consciousness, then you take all kinds of... All the well, all the purpose of different type of well is served in the river of Krsna consciousness.
