Derived from Sanskrit कल्किन् kalkin, "foul, dirty, wicked, having sediment, turbid."
"Subjective rationalism is the basis for Kalkian personalities. Let us understand by “Kalkian personalities” those pseudo-esotericist, pseudo-occultist, and pseudo-scientist people from this modern epoch, along with all of their know-it-all types of foolishness. Never has there been as much darkness as there is in this epoch of Kali Yuga." - Samael Aun Weor, Cosmic Ships
