Stopping Tanha or craving If one of the goals to becoming enlightened is to lose all craving, desire or Tanha how is one to do that without the craving, desire or tanha to do just that. In other words, is wanting to eradicate all craving and desires a craving or desire itself?
This is a very common misreading of the four noble truths.  Don't feel bad; you've got a lot of company!  The Buddha never actually said that all craving is bad.  In the 2nd noble truth, he is very specific about the kind of craving his path seeks to eradicate.

And this, monks, is the noble truth of the origination of stress: the
craving that makes for further becoming — accompanied by passion &amp;
delight, relishing now here &amp; now there — i.e., craving for sensual
pleasure, craving for becoming, craving for non-becoming.
from the Dhammacakkappavattana Sutta

The third noble truth is the extinction of that kind of craving -

And this, monks, is the noble truth of the cessation of stress: the
remainderless fading &amp; cessation, renunciation, relinquishment,
release, &amp; letting go of that very craving.
from the Dhammacakkappavattana Sutta

The desire that truly seeks liberation is not the same mind that craves for sensual pleasure, becoming, or not becoming.  Sure, there are people who begin practice because they believe that enlightenment will add something to their personality - as if nirvana will bring about something they are otherwise lacking.  Perhaps they crave for the pleasure of meditative absorption or believe that the wisdom that the path generates will give them a sense of personal power.  Perhaps they believe that the Buddhist path will lead to some sort of Schopenhauer paradise of pure nothingness.  Those lesser desires  for liberation need to be given up if one is to proceed past a certain point.  But the desire to put a final end to suffering?  If it's pure, there's nothing wrong with that.
