In plain words
So, if you find just one whose citta is steady, it is enough. However many thousands there may be whose citta is fickle, the world gains nothing from them. Once, while Rāmakṛṣṇa Paramahaṃsa was scattering sacred words, Rāṇi Rāsamaṇi was there, pretending to listen. At once Rāmakṛṣṇa, who was teaching, went up and struck Rāṇi Rāsamaṇi two (handed her two, that is) on the cheek. But all who had gathered there: ‘She is the Rāṇi, after all; while this woman was happily taking part in this gathering and listening to all these words, such a notion arose in the Swami. He has insulted her in front of so many people! Has he lost his mind?’ they imagined. But Rāsamaṇi too, as one who knew nothing: What wrong is there? Why has he shamed me like this? She too could not see her own fault, and fell prey to many kinds of misapprehension. If people recognised their own faults, they would make no faults at all. In the same way, Rāṇi Rāsamaṇi too went on imagining that she had done nothing wrong. At once Rāmakṛṣṇa noticed it: ‘Are you sitting here to listen to my teachings, or to think about court affairs? If you mean to think about court affairs, go home and think about them. There is no need to sit in this place. I will not forgive at all a body that defiles time,’ he rebuked her sharply. In the same way, among those of us who have come here and sat down to listen, some are fools who sway like the aśvattha tree, some are people who look this way and that like crows, and some listen carelessly, somehow, to what is being said. Some are the very picture of disorder, who do not even know how to sit; by sitting in this gathering, such people end up teaching others some bad habits. So, when we take part in a gathering like this, we must make the effort it needs to become steady in citta. Whatever the circumstances, the nature of those steady in citta gives them the chance to feel that they are dedicated to the principle of the Ātma alone.
