(Loving kindness) Feeling that kind of completeness is a life long journey friend. One that comes with pit falls of extreme ups and downs, and many never reach.

The key is not accumulating all that you've learned, but disregarding what is unnecessary in your path to Metta. That's what my journey through Dao's taught me at least.
