vism iii56> Iddhīti pothujjanikā iddhi.
Sā hi uttānaseyyakadārako viya taruṇasassaṃ viya ca dupparihārā hoti.
Appamattakeneva bhijjati.

They are hard to maintain, like a prone infant or like young corn,and the slightest thing breaks them.
But they are an impediment for insight, not for concentration, since they are obtainable through concentration.
Tasmā vipassanatthikena iddhipalibodho upacchinditabbo, itarena avasesāti ayaṃ tāva palibodhakathāya vitthāro.

The Visuddhimagga explains that the vism iii29 > he should sever any of the ten impediments that he may have.
A dwelling, family, and gain, A class, and building too as
fifth, And travel, kin, affliction, books, And supernormal powers: ten.
This can help us see the different ways of insight and samatha.
So the supernormal powers are an impediment that should be severed by one who seeks insight; the others are impediments to be severed by one who seeks concentration. This, in the first place, is the detailed explanation of the impediments
