By increasing the amount of light you. bring in you can increase the size of your field.
I'm such a dolt sometimes - not getting that you were writing about your energy field.
Most people don't get that I have big field on a transpersonal level. Most people are wrapped up in the insecurities of themselves to notice other people let alone the size of fields. Of themselves or others.
Even people who appear to have a big ego (and a big field too) are unaware of the size of their field and overcompensate in their writing and responses. One or two people I've encountered on Medium have that problem. They are wonderful men without trying so hard.
Many robust egos - men mostly - have big fields and of those about 1/16th are obnoxious and unaware of it.
