Learning to manage the ascent, without rushing. Also because you wouldn't want too much energy in your brain all at once without first having a way to physically adapt to the amount of new energy. I tried to stay with too much energy in the throat chakra and I wanted to die (figurative speak of course, but it was physical torture, I have never had such a bad spiritual experience because I had a blockage that didn't allow for ascent and the buildup was really killing me. It was getting worse and worse and it became impossible to lead a normal life). Too much energy is not good, so learn to manage the ascent and not just focus on the ascent.
