Relaxation Program

-- Change log: V1.1: All I did was clean up the code a little to bit to make it look nicer and easier to read. The code itself isn't any different at all (Except for changing 10+1-i to 11-i. I don't know what I was thinking when I did that part; I probably wasn't xD).
local sides = {"top","bottom","left","right","front","back"}
local instr = {
  [1]="A note block is required for audio cues.",
  [2]="Make sure the note block is making a sound that is both audible and pleasant to you.",
  [3]="Relax yourself:",
  [4]="Get into a comfortable position.",
  [5]="Close your eyes.",
  [6]="Listen for audio cues.",
  [7]="Inhale through your nose for 5 seconds.",
  [8]="Hold for 3 seconds.",
  [9]="Exhale through your mouth for 8 seconds.",
  [10]="Repeat 10 times.",
  [11]="Press any key when you're ready to begin.",
  [12]="A sound indicating to begin will play in 10 seconds.",
  [13]="A sound will play twice once finished.",
  [14]="If time is a concern, this practice only takes less than 3 minutes.",
  [15]="This session is now finished. I hope you have a relaxing rest of your day."
