We are not much concerned about the temple because temple worship is not primary factor in this age. Primary factor is Sankirtana. But sometimes we want a center where people may gather and see, so a temple is required secondarily.
Letter to Mukunda – New Vrindaban 27 May, 1969.
Sukadeva Goswami says, this age is an ocean of faults, but there is one boon, in this age one gets the same result as was achieved in former ages through elaborate temple worship, costly sacrifices, or introspective meditation, simply by chanting the Holy Name of The Lord.
Letter to Achyutananda, 1975.
Sankirtana will always be appreciated, because it is the special blessings of Lord Caitanya Mahaprabhu on the people of this fallen age of Kali.
Letter to Achyutananda, 1975.
Everyone should be given a chance to take prasada and thus be induced to chant the holy names of Hare Krishna and also dance in ecstasy. By these three processes, although performed without knowledge or education, even even a dog went back to Godhead.
Chaitanya Caritamrta Antya Lila 1.32
The Krishna consciousness movement is based on this principle: chant the Hare Krishna mantra at every moment, as much as possible, both inside and outside of the temples, and as far as possible distribute prasada.
Sankirtana means chanting of the holy name of the Lord.
Purport on Srimad Bhagavatam 7.15.7
The conditioned soul sometimes personally appreciates the futility of sense enjoyment in the material world, and he sometimes considers material enjoyment to be full of miseries. However, due to his strong bodily conception, his memory is destroyed, and again and again he runs after material enjoyment, just as an animal runs after a mirage in the desert.
“In it, even that far back, Prabhupada spelled out his clear vision for spreading his mission in four distinct and closely connected movements or waves.”
When a man is attached to material enjoyment, he is attached to many miserable conditions, but nevertheless he accepts his condemned position as one of happiness. Sense enjoyment is so strong for such a person that he cannot give it up, exactly as a worm in stool cannot give up the stool. From the spiritual point of view, when a person is too absorbed in material enjoyment, he is exactly like a worm in stool. Although such a position is utterly miserable to the eyes of liberated souls, the materialistic enjoyer is greatly attached to it.
Hear first, then glorify.
