It is very easy to distinguish these three parts when we begin to observe ourselves. Mechanical parts do not need attention. Emotional parts need strong interest or identification, attention without effort or intention, for attention is drawn and kept by the attraction of the object itself. And in the intellectual parts you have to control your attention. When you get accustomed to control attention, you will see at once what I mean. First the character of the action will show you which centre you are in, and then observation of attention will show you the part of centre. It is particularly important to observe the emotional parts and to study the things that attract and keep the attention, because they produce imagination. Study of attention is a very important part of self-study, and if you begin to observe this division of centres into parts, in addition to the division of centres themselves, it will give you the possibility of coming to smaller details and will help you to study attention.
