I have already added seventy-three essences into the and have to add eighty-four more.

I had failed seven times already and this was my eighth attempt; I don't want to fail, but it is damn hard. 

I had to manage and merge the essence that would burn each other contact while keeping the keep the heat on them, which is healing them from all sides. My head is sweating and so is my back and I haven't finished even half the work yet.

As the energies balanced, I added another essence into the mix, and once again; it had come on the verge of explosion, which I again thwarted with nine fires.
