It is just my opinion, but I think that both feeling guilt, as well as the need to apologize, is nothing less than to completely deny the wisdom of your role in the world, to deny your own dharma or duty as though it is a mistake, to deny that you behaved in the only way possible for you to do so at any particular time in one’s life. To me, the process of feeling guilt and then apologizing just seem like a mistake, a slap in the face of your own Higher Self.
Those who serve their purpose and do what they are here to do have no need to apologize for anything, no matter what happens. Even the act of just taking time to apologize for one’s true, intended actions is taking time away from your purpose in life. Let your intentions be pure and selfless. And then…Just do. But do not apologize. No guilt. No shame. No apologies. Not now. Not ever.
Such are the actions of a God-united being.
