I agree. If Mary is in heaven, she and others of us who are there (believers) have no idea what’s going on down here. There will be no tears in heaven. If they were aware of what’s going on down here with those they love, they would have tears and plenty of them. And they wouldn’t have much peace and comfort either.
I wouldn’t want to be emphatic in assuming that every last Heavenly resting believers knows 100% absolutely nothing about anything down here, ever. God makes exceptions to even His rules somewhat often.
I do believe that generally, such things are screened out of their awareness affording them maximum joy, peace, rest, serenity at this time.
