This field is created to help you to connect to your Akashic Records. It will prepare your system and consciousness for this beautiful trip. It has to be used with a calm mind, body and neutral emotional state.
Remember always to make good preparation and put protections on you before you travel. We already have many protective fields for this use.
If I understand correctly the premise of your question is that this field changes the Akashic record. This field gives you a connection to the record, it does not alter it in any way. What you do when you connect is up to you.
I meant that does the usage of any Maitreya fields alter the records?
I assume that any Maitreya fields would be used by me is in the records as well and the information I access after any MF field is just a different set of information from what I would have accessed without using Maitreya Fields.
Every change you make with the fields you use from us or with your own internal realizations and self-improvement can lead to changes in your Akashic records. If the things you change are related to karma, lessons, and virtues, this will have the greatest impact.
However, this is not due to a specific field, but rather things happen automatically this way for all beings.
