Pradyumna (reading): "Śrīla Rūpa Gosvāmī has given a definition of auspiciousness. He says that actual auspiciousness means welfare activities for all the people of the world."
Prabhupāda: Yes. Just like this Kṛṣṇa consciousness movement: it is welfare activities for all the people of the world. It is not a sectarian movement; not only for the human being, but also for the animals, birds, beasts, trees, everyone. This discussion was made by Haridāsa Ṭhākura with Lord Caitanya. In that statement, Haridāsa Ṭhākura affirmed it that by chanting Hare Kṛṣṇa mantra loudly, the trees, the birds, the beasts—everyone—will be benefited. This is the statement of Namācārya Haridāsa Ṭhākura. So when we chant Hare Kṛṣṇa mantra loudly, it is beneficial for everyone.
This statement was put forward in Melbourne in the court. The, the court inquired that "Why do you chant Hare Kṛṣṇa mantra loudly in the street?" The reply we gave, that "Just to benefit all the people." Actually, it is the fact. Of course, now there is no prosecution by the state. We are chanting very freely on the streets. That is the benefit. If we chant Hare Kṛṣṇa mantra, it benefits everyone, not only human being. My Guru Mahārāja used to say if somebody complained that "We go and chant, but nobody attends our meeting," so Guru Mahārāja would reply that "Why? The four walls will hear you. That is sufficient. Don't be disappointed. Go on chanting. If there are four walls, they will hear. That's all." So chanting is so effective that it benefits even the animals, beasts, birds, insects, everyone.
