Yes Many names,
The guru tells us in jaap sahib,
"tav sarab naam kathe kavan, Karam naam barnat sumat"**
"None can truly express or give
discourse on your names, it is by your actions that you are named the wise know this."
Similaraly the same is found in EXODUS 3:6 of the Torah/Bible
The Holy One, Blessed Be He, said to those, you want to know my name? I am called according to my actions. When I judge the creatures I am Elohim, and when I have mercy with My world, I am named YHVH Ex 3:6
The guru and God have given us
Waheguru
the force of extacy that drives one from the darkness into the light
this name waheguru is also a culmination of the different names for god through the 4 ages
*W*ashadev ( the one who pervades everywhere)
*H*ari ( the one who blossoms within)
*G*obind (the lord of all creation)
*R*aam (the giver of bliss)
but when we refer to god our names are very practical.
Akal = the timless one / beyound death and deteriation
Waheguru = the ofrce of extacy which drives us out of the darkness into the light
Akal Purakh = the timless being
Satnam = Whoes name is truth
Kartar= the creator
Har/ hari = the one who blossoms within the heart
May the lord bless you on your life journey
