The first attention works very well with the unknown. It blocks it; it denies it so fiercely that in the end, the unknown doesn't exist for the first attention.
Taking an inventory makes us invulnerable. That is why the inventory came into existence in the first place.
The first attention consumes all the glow of awareness that human beings have, and not an iota of energy is left free. So, the new seers proposed that warriors, since they have to enter into the unknown, have to save their energy. But where are they going to get energy, if all of it is taken? They'll get it from eradicating unnecessary habits. Eradicating unnecessary habits detaches awareness from self- reflection and allows it the freedom to focus on something else.

The unknown is forever present, but it is outside the possibility of our normal awareness. The unknown is the superfluous part of the average man. And it is superfluous because the average man doesn't have enough free energy to grasp it.
