In plain words
So it is far better for us to take part in saṅkīrtana than in kīrtana. We can sit in solitude, sing God's praise and enjoy some Ānanda by ourselves. We must experience community prayers. We must offer them. We must develop them. The one who first began this, community saṅkīrtana, was Guru Nānak. He went on believing that through community kīrtana of this kind all mankind could be carried across. As it is said, 'Eko vasi sarvabhūtāntarātma', when one Name is uttered once among all, the light called divinity shines in all. 'Brahmavid brahmaiva bhavati': one who has recognised the principle of Brahman can become Brahman itself. In the same way, one who has spent his life in nāma-saṅkīrtana can become the Named.
Even Ratnākara, a great villain and a wicked man, sat in an anthill and thought of the Name of Rāma, 'Rāma, Rāma, Rāma'; and because he did, the radiance of Rāma was reflected in the face of this Vālmīki. All this radiance of Rāma's compassion arose in Vālmīki's face itself. Vālmīki shone as one whose very form was radiance. In that very radiance the Rāmāyaṇa was born. Moses too, who ever thought of God: because this man too ever thought of God, the radiance of God sprang forth in this Moses as well. Prahlāda, born in a race of rākṣasas: by this very thought of Nārāyaṇa, ever 'Nārāyaṇa, Nārāyaṇa', his form became radiant. So the thought of the Name is not something that gives only a passing joy. What brings lasting, eternal, true, unbroken Ānanda is the Name. For the moment we may call this emotion. We may call it excitement. But those are not the right words. But when we make this Name a community saṅkīrtana, we must hold our attention on the community. It must be in an easy way that everyone can follow. It is not good for you to enjoy selfishly only your own pitch, your own rāga, your own bhāva. When many people gather, we must say that Name in a way that is easy for all to utter.
If you go on singing songs others cannot follow, if you utter a Name no one else can take up, it is merely flat. Zest and gaiety do not arise in it. In a state where others cannot follow it, their minds keep changing in many ways. We must not give room for such a thing. When all, turned with one mind, say the Name at one time, what divine Ānanda arises in us!
