A repeated meditation experience and some UPG about the rune Isa:
I’ve added the Elder Futhark rune Isa to my list of runes for trancework — with Isa as the grounding/anchoring rune.
During several meditation sessions, L suggested that I trace the rune Isa onto my hands (and sometimes, onto the top of each foot). At first, I thought the reason for it had something to do with slowing down or halting the wave of anxiety that I felt during trancework, as I often felt anxious over feeling too ‘light’ (weightless) or disconnected from my body (or from the Earth itself) during meditation.
Tracing Isa on the backs of both hands or on the top of each foot served to lessen those sensations, and helped me to anchor myself. (Meanwhile, marking a single hand or foot gave me the sensation of being similar to a balloon tethered by a string, i.e the singularly marked hand or foot felt as if it was the only means that rooted me to the ground – which in my experience was yet another [albeit slighter] anxiety-inducing sensation indeed!)
Nonetheless, I can see how others may prefer marking a single hand or foot, as it may better suit their needs.
In short, your mileage may vary.
As well, I learned that magically, Isa can be invoked as a powerful rune for shielding and protection, as Isa can be called upon to take the heat out of a confrontation, as well as to shield oneself/as protection from magical attack.
