(These plants were all over the flower beds around my country aunts home as I grew up!!)
Mudra, The poem is beautiful!! It is similar to a practice that I was taught....
I was taught as I lay down to sleep....To release negativity from my body to each of those directions to be transmuted to more useful purpose and to draw light onto myself from all those directions...of course,calling on each of the directions seperately....
It is immensely helpful and relaxing to go into sleep with one's aura cleansed!!
Blessings all!!
