Maintaining a diary is widely recommended as something that helps making progress. For this course in Integral Indian psychology there are some additional reasons to do it. The first is, that in Indian psychology one uses one's own nature as an instrument for making psychological observations, and maintaining a diary creates a perfect occasion to train this capacity. A second reason is that we look at our own progress not only as a private, individual project, but also as part of a collective process of evolution. In other words, good self-observations are not only valuable for oneself, but they can also help in theory formation and the development of know-how that's useful for others. Finally, if one maintains one's diary in a systematic manner, it might produce a trail of slow, long term changes that escape notice while happening, but that can provide valuable insights both in one's own nature, and in the more generic processes involved in long term change.
In most of us, our short term memory fades surprisingly fast, so it is best to make entries as soon as possible after the psychological events one wants to describe. One can see how often one can manage to do this. During an intensive course on Indian psychology one should do it at least once a day, but more often is better. Good times for making a short entry are immediately after a class, a meditation, a dream, any event of interest. You will see that the sooner one does it, the more details one can collect, and it tends to be the fine details that make the entry interesting. If one doesn't have time to write, one can try find at least a minute or two to be silent and describe it in one's mind for later recall.
As a whole it is strongly recommended to write the diary as if you will be the only one who will read it, ever. This makes it much more easy to be fully honest. One can decide later how much of it one might like to share and with whom.
It is not essential, but giving a structure to one's diary helps in two ways:
The tags can be given while writing the diary, but if that disturbs the flow, they can also be added later. You can see how many different tags you want to use. There are arguments for small lists of main categories (say: event, tool, plan, evaluation, overview) as well as for long, or even unlimited lists. It is ok to use different tags for one single passage (for example, "tool" and "silencing the mind"). Below is a longish list of sample tags, but whatever works best for you is fine. Once in a while you may like to go back to the list given here and see if you are inadvertently skipping certain categories while writing your diary. For most people it works best to start with a short list. If a tag gets too many entries, you can always split it later.The following tags were used by students during the first IPI course given on the basis of this outline:
Whatever you do about the tags, do write your diary, in as much detail as you can manage, and always give the date of the entry!
The usefulness of the diary gets multiplied many times if combined with an "individual, yoga-based, first-person mini-project".
