I agree with Anthony and Tyler here, and I'll add that I would not say speaking self-forgiveness is pointless, and writing self-forgiveness is the only way to go. From my perspective, B in the vlog was pushing the point of sharing ourselves, and our process - in writing - to be visible, and standing up as not only supporting ourselves, but others as well. In a way saying the only way we can trust ourselves and each other is to SEE in writing our self-forgiveness, though I would not say this is absolute. For me - I can see in my words when I've been living self-forgiveness, whether written or spoken out loud to myself, it's apparent in who I am as the words I write, and so the same goes for others as well. You can see in each one's words where they are, and whether one is living self-forgiveness. So it's more a matter of ensuring we are not bullshitting ourselves or others - to have it physically seen who we are as our writings/self-forgiveness
So I see it as it's important that we are visible in our sharing, and our writings, for ourselves and others, though not to think it must be 'this way' or 'that way' ONLY. It's about self... self-honesty.
As of late, I've been mostly writing my self-forgiveness, though this is due to a resistance to speaking the self-forgiveness, which I am still walking/pushing through. In the beginning of my process, I spoke my self-forgiveness out loud, and I'll tell you - I experienced quite an obvious effect in the actual releasing of the points I was speaking forgiveness on - literally feeling myself become lighter and centering within myself. So there is an absolute effect on the SOUND of our voice, with self-forgiveness - the resonance of our sound, and how that influence the resonance of our mind/body/being.
There are many interviews on Eqafe as well that speak about this point of Sounding our Self-forgiveness - the Atlanteans interviews are literally taking on specific emotions/feelings and the SOUND in which to speak our self-forgiveness to direct the patterns within those energies.
So don't make it absolute - this or that, one way is the only way. Investigate and test out what works for YOU! If there are ideas about what is 'right' or 'wrong' - clear that up with self-forgiveness and realize the most effect your self-forgiveness has on you/your life is coming from YOU as the starting point from which you apply it.
Play with it - write it out, speak it out, do both even. I was applying that for awhile as well - writing it out, then going back and sounding it to ensure I was standing within my words, and speaking in a way where I was taking responsibility for what I was forgiving. I found that to create much stability as well.
It's your process - so see what works for you.
