Long before I learnt Yoga asanas and kriyas, I learnt from my parents the importance and sacrednes of having a meditation mat (dhyana asana).The concept of asana as a physical position has been over explored along with having an appropriate Yoga mat, however the concept of having a mediation mat for mediation is mostly ignored.
