KSSH of the Arizal IS NOT the one we have in our Sedurim!!
It is different selsction of tehilim and tefilos plus one Kabalistic viduy which should not be said by just anybody
Can you tell me why you need to come to the coffee room to ask.
Did someone recommend it to you? Then ask him to tell you what it is all about.
If I remember correctly the Tehilas Hashem (Chabad)Sidur’s version is at least in part based on the KSSH of the Arizal
