Well, this is the number one thing to recommend whether you're in a meditation center or whether you're out of a meditation center, is the Kalyanamitta, the good, kind, wise spiritual friend. There's nothing that can be recommended higher than that. There's a listing somewhere in the scriptures, the Buddha explained Seven Suitable Conditions which will help you speed up your growth, develop wisdom and so on, Seven Suitable Conditions. Some of them are just physical things, like environment, food, clothing, etc. They're physical. Now, say for me, if I had to live in a very cold climate for twelve months a year it's not going to be suitable, it doesn't match my personality, it will just be too cold and I'll be working against the cold, staying indoors, etc. So for me it's not a suitable environment to be where it's too cold. If I get fed lots of chilies in Thailand, it's going to upset my stomach, it won't be suitable for me, it will create too many physical problems and I can't do the mental work then. So we can see how those suitables work. Within these seven though, five of them are more on the material side and two of them are not. And the two that are not are: to have good, kind, wise spiritual friends, Noble Friendship, and to have Noble Conversation, that is to be talking about inspiring things, to be talking about the practice, etc. Those two are supreme amongst the whole seven. If you have those two, the other seven aren't that important. I could be in a cold place if I had a good, kind, wise spiritual friend and if I had constant good conversation. I could be eating chilies every day and not worry about my upset stomach if I had a good, kind friend sitting there next to me eating and giving me good conversation. So in a nutshell, as far as what's most important in the whole practice; a good, kind, wise spiritual friend and noble conversation.
