| "There are many yogīs: karma-yogī, jñāna-yogī, dhyāna-yogī, hatha-yogī, bhakti-yogī. Yoga system is just like a staircase. Just like in New York, that Empire State Building, that 102-story building, so there is a staircase or a lift. So yoga system is just like a lift to go to the highest perfection of life. But there are different, I mean to say, flats. Just like karma-yoga. You can approach, you can make progress to the first or second floor. Similarly, by jñāna-yoga, you can make progress to the fiftieth floor. And similarly, by dhyāna-yoga, you can make progress up to the eightieth floor. But by bhakti-yoga, you can go to the highest platform. This is also very nicely explained in the Bhagavad-gītā, bhaktyā mām abhijānāti (BG 18.55). 'If you want to know Me cent percent, then come to this bhakti-yoga.' And this bhakti-yoga means this śravaṇam. The first thing is śravaṇam and kīrtanam. You simply chant and hear, simple process."
