I am a big fan of the float tank - an hour's sensory deprivation to restore mind and body. I recently spent some time in this one at Yue Float and feel as good as new.
I also used the ajna light alongside the para light pad. Now this is totally trippy - I've no idea how it really works but I felt awesome after. Apparently it stimulates the pineal gland during meditation and takes you into different brainwave states.
This was my favourite treatment - extraordinarily effective. I chose to go into Theta as rapidly as possible (spot the man who's not been getting enough sleep) and it felt good.
