SUMMARY
At the end of Hajj, what one realizes is all the rites of Hajj are indeed lessons, ethics and morals (Akhlaq). When one has completed the Hajj, the correct etiquettes is to visit the prophet (saws) and his ahl al-bayt (a.s); and to pay one's respect to them while seeking their intercessions in all acts of worship for Allah says in Chapter 4 vs 64:

"We sent no Messenger, but to be obeyed by Allah's Leave. If they (hypocrites), when they had been unjust to themselves, had come to you (Muhammad SAW) and begged Allah's Forgiveness, and the Messenger had begged forgiveness for them: indeed, they would have found Allah All-Forgiving (One Who accepts repentance), Most Merciful."

This then starts one's journey back to the creation. The prove that one's Hajj has been accepted is weather one's life is different from what it was before performing the Hajj. If one is now more diligent in one's salat, and one's etiquettes and morals have improved, if one has given up all ways of wrongs and sins, if one's goal and ambitions in life are now more focused on the hereafter than on this world, if one's service towards mankind is more, then indeed this is a sign of having one's Hajj accepted. For in the Four journeys of Mulla Sadra, the 3rd and the 4th are the most difficult i.e the journey back to the creation and remaining with Allah while remaining with the creation for rest of one's life.
Hajj is therefore more than just of fulfilling religious obligations. It is your submission and acknowledgment to the fact that it is now time to change the course of your life and to set things aright.

May Allah make us of those in whose Hajj has been accepted; and provide means for we who has not been to Hajj but has a great desire in doing so.
