```I think the original poster may be new to coding, in which case, can I
recommend the first couple of chapters of "_Why's Poignant Guide to
Ruby"?  People tend to either find it really useful, or hate it, I
think.  http://poignantguide.net/ruby/

At the risk of adding even more meat to the pot:

def numerologise(name)
# turn name into an array of integers
arr = name.upcase.unpack("C*").map{|x| (x - ?A) % 9 + 1}

# keep going until there's only one integer in the array
until (arr.size == 1)
# add up all the integers
tot = arr.inject{|c,x| c + x}

# split the digits to make a new array
arr = tot.to_s.split(//).map{|y| y.to_i}
end

return arr
end

puts numerologise("ruby")

(This is basically Sebastian's original answer, although perhaps it's
easier to understand like this.)

Me, I imagine places that I have never seen / The colored lights in
fountains, blue and green / And I imagine places that I will never go
/ Behind these clouds that hang here dark and low
But it's there when I'm holding you / There when I'm sleeping too /
There when there's nothing left of me / Hanging out behind the
burned-out factories / Out of reach but leading me / Into the
beautiful sea
