"...So who will be the new ראש of America? Our readers probably will be shocked to learn that 501 is also the gematria of ברק חוסיין אובאמה, Barack Hussein Obama. ..."[/B] Varian, 'rosh' or 'head' is definitely something that gives direction to the mind, to the body etc.
Another 501-word that gives direction is 'asher' and has multiple meanings as conjunction. One is used by God in perhaps the most meaningful way to make the essence of BEING understandable; "I am who I am" or in a more free translation "I will ever be what I am now"

So I think it is important to think primary about 501 (when comprised of aleph/shin/resh) as something that enables knowledge of who you are and in extension... what is and isn't part of you.
