We tend to believe in the modern secular world that if you tell someone something once, they'll remember it. ... Religions go, "Nonsense. You need to keep repeating the lesson 10 times a day. So get on your knees and repeat it." That's what all religions tell us: "Get on your knees and repeat it 10 or 20 or 15 times a day." Otherwise our minds are like sieves.
You know, in the case of most of us, the mind is noisy, everlastingly chattering to itself, soliloquizing or chattering about something, or trying to talk to itself, to convince itself of something; it is always moving, noisy.
