If i am the result of an aggregate, how does one refer to oneself? It is my understanding that illusion, reality, rebirth and reincarnation are a result of the aggregates i.e. vision, taste, sound, emotions, smell and mind. - Source

If one is am simply a composition of these aggregates, how does one refer to oneself in everyday conversation? For example, when using the term i, in sentences such as i am ..

The reason for the question is to step away from being attached to one's identity which is generally reflected in i.
Short Answer: Use "I" like you always did, but be mindful of what it does (and doesn't) refer to.  

Longer Answer:

It isn't that "I" doesn't exist; rather, it doesn't exist in the way we normally think it does.  "I" does not denote a stable, independent entity that is "us". 

However, "I" does exist in another sense; it's Conventionally Real. For instance, imagine you are with friends and you say something.  Then someone asks "Who said that?". How will you respond?  Will you say...


The Skhandas did? 
Talking is happening?
This biological unit has spoken?


I hope not! You can respond with "I did", because that is the correct response.  After all, the other people didn't say that; if they didn't say that, then who did?  Further, if you talk about other people normally, but talk oddly about yourself, then aren't you still clinging to yourself, by holding yourself out as something different than what's around you?  Clinging is clinging; it doesn't magically stop being clinging because you clung to something different. 

The issue isn't using "I", but your beliefs about it. Although language can affect thought, changing your words won't necessarily address the problem.  It's the thoughts and feelings behind those words that matter.  

Words are meant to be used publicly, and as such, conventional rules regarding them should be observed if they are to be used effectively.  However, be mindful of those words; gauge the impact of certain words on your mind. When you say "I" are you really just being conventionally real, or is there a trace of clinging to self when those words leave your lips?  What feelings arise from using "I" when you are criticized or praised or threatened?

If you talk funny, you won't gain enlightenment; you'll just lose the ability to coherently communicate.
