In plain words
A fine example. As is the fire we light, just such is the smoke that comes. As is the smoke that comes, such are the clouds it takes shape as. As are the clouds, such is the rain that falls. As is the rain, such is the crop that grows. As is the crop, such is the cooking. As is the cooking, such is the Buddhi. So our Buddhi depends on the karma we have done. That is why they said, 'Buddhi karmānusāriṇī'. When we practise our karmas as good karmas and contemplate with good feelings, we see only good results. So: 'Yadbhāvaṃ tadbhavati'. We must develop our feelings so that they are pure and holy. This uttering of the Name is most divine. With this Name we can forget even the form. We can be merged in a state of Ānanda. Of himself a man can become wholly absorbed. People can become enraptured. He can experience the principle of sweetness. This itself they called the state of samādhi. If we are to attain such a state of samādhi, it lies only in the karmas we do.
So we must not think of nāma-saṅkīrtana as merely some bhajan and set about it only to pass that time pleasantly. When thousands of people gather, we must utter only Names that are within reach of all, convenient, and in a fitting, easy way. As we sing this Name, the bodies must of themselves swing in caitanya. If we sing slow, as if going to sleep, that gathering too sinks into tamo-guṇa. So the saṅkīrtana of the people of Bhārata is most holy. I have told you many times what Bhārata means. It is made up of three letters, bhā, ra and ta. 'Bhā' means bhāva; 'ra' means rāga. 'Ta' means tāla. Bhārata is that which is a blend of bhāva, rāga and tāla. When you keep tāla with bhāva, with the mouth, with rāga, you must of yourselves be transformed, wholly absorbed. When the hearts of all come together in one place, when the voices of all join in one pitch, when the beats of all fall in one rhythm, what Ānanda there is! This is the true form of caitanya. If we take only the joy of our senses, our own rāga, our own note, it becomes nothing but sheer selfishness. So we must drive off this sense of 'mine'. We must make all mankind one. Through oneness of this kind we can experience this divinity. So we must develop this saṅkīrtana that we do as unity. Where there is unity, there is purity.
