The living entitiy attracted by maya is attributed with four types of anarthas: hrdaya-daurbalya (weakness of heart), aparadha (all kinds of offenses), asat-trsnA (material desires), and tattva-vibhrama (illusion about spiritual knowledge).

Sva-tattva-bhrama, (illusion regarding one's own identity),
paratat-tva-bhrama (illusion regarding the Supreme Personality of Godhead), sAdhya-bhrama (illusion regarding the process of prema-bhakti), and sAdhana-brhama (illusion regarding the process of sAdhana) are the four kinds of illusion found in conditioned souls.
