I read somewhere at that someone made their energy conversion box very small, which I tried to do as normally my one was huge, up to my waist.

The purpose for making it small maybe to tell your subconscious that your problems are small. I think looking at it that way helps.

Then I realised, why stop at putting your current issues into the box? Assuming that we are an eternal awareness inhabiting a temporary flash body with many thoughts and desires and fears associated with the human mind, why not imagine putting everything of the mind into the box?

So that's what I do now- I imagine a very small container, and imagine my issues, then mind, then body dissolving into a wave and getting sucked into the box, a bit like the final scene of raiders of the lost ark.

After doing this I imagine that I'm now my pure awareness, without the baggage of the human body or mind, and I feel lighter and the wave seem easier to do.
