How do Ancestors access the fields?
It‘s more passively right? How would they know that I have sent them into the System?
It‘s not like they have Phones and can choose which one they need now
Does it happen subconsciously? Or do their higher Selves access the fields?
Through the egregore of the lineage, the fields enter the system and the ancestors who need these changes — the fields enter their consciousness. After their death, they are not unconscious, but they possess a different kind of consciousness.
Ahhh so, they don‘t get the field, while they live?
I thought I was sending the fields to the past, and my Ancestors could use them while they lived.
This field is more for their Souls, but for the Ones that still live, and they are a lot, they can also use them now right?
Like my Parents, my brother, my Aunts, Uncles, Cousins etc.
They receive it, but unconsciously, through their consciousness which is within the ancestral system.
It may even change fateful decisions in their lives and allow them to do things better than they were able to before, without these understandings and energies.
Okay wow, but this doesn‘t mean I will suddenly disappear right
Like in the Movies when someone changes the past and they stop existing 
Your ideas are just… /chef’s kiss
I‘m experiencing a surge of Energy right now. My body feels so Electrically charged.
I will keep the fields on and use Nervous System night field and Grounding for the whole night.
I don‘t know what‘s happening but it must be good 
Okay I‘m definitely experiencing Energy Overload here.
Any Tips on which Fields to keep focused on? And which ones tend to be hard on the System when Ancestors use them?
Give them unconditional love so they can be in a better state of mind and accept things more easily. The Acceptance virtue can also help.
Since there has been a lot of immigration in my family, I want to trace the whole movement and pay homage to the land my ancestors lived through. What would be a good way to approach this?
I added the giving and receiving love to the folder along with unconditional love which was there since before. I know this will clean the flow through the system.
