How can a person walking Spiritual Path suffer more than someone who does not ?

Mystic Musing Pg 164

"Seeker: So Sadhguru, every time someone is born he just gets a pack of
karma to work out in this lifetime?

Sadhguru: The warehouse is there. One truckload has been taken out, to be worked
out now. The warehouse is always sitting there in your head. Now what we're doing
with Samyama, you're not going into the prarabdha. You're going into the sanchit
aspect of your karma. You're bringing out, you are opening up the warehouse. That's
the reason why, when a person walks the spiritual path, in many ways---if they don't
handle the situation properly---they will suffer much more than someone else, because
they are bringing up large volumes of it. Others are just handling what is allotted to
them. Now you're trying to take up the whole portion, you want to get your PhD today,
so you're not going step by step. That is the reason why so much discipline was always
brought into yogic practices, so that when things overwhelm you, you are able to
handle that situation. Otherwise, if you open up things for which you are not ready,
karma can just smother you completely."

So, we are just opening Pandora's box on a spiritual path? It makes sense. That's why we need a Guru.
