genitive plural of the compound vitakka-vicāra (literally "applied thought and sustained thought"); here agreeing with a neuter plural noun
Analysis. vitakka (from vi + takka, "thought thrown out in different directions") + vicāra (from vi + cāra, "examination going around the object"); together they denote the initial directing and sustained probing of the mind toward a meditation object, the first two jhāna-factors paired as a compound.
Etymology. Both components use vi- (apart, asunder, intensive clarity). takka derives from the root √takk- (to think, to cognize). cāra derives from √car- (to move, walk), so vicāra is literally "moving around", scrutiny. In doctrinal usage, vitakka and vicāra represent coarse and subtle grades of mental engagement; they fall away in the second jhāna when the mind becomes steadier.
