The richness of human personality is astounding, and a single trait cannot fully characterize it. It's hard to understand how personality qualities are linked to variances between people. This article examines personality formation via the framework of Indian philosophical concepts, particularly panchmahabhuta, panchkosha, triguna, and tridosha. Using a qualitative research approach, this retrospective study methodically gathered and examined pertinent material from traditional texts of both orthodox and heterodox schools of ancient India. The results show a range of views on how people form their personalities. The panchkosha vyaktitva vikas theory explains how personality develops via five layers: annamaya kosha, pranamaya kosha, manomaya kosha, vijayamaya kosha, and anandamaya kosha. The tridosha and trigunas theories show how the panchmahabhuta (five great elements) affect personality via physiological fluids (vata, pitta, and kapha) and the three gunas (sattva, rajas, and tamas). It is clear that everyone has all three gunas and doshas, but the amounts of each one that a person has make them distinct in terms of personality and psycho-cognitive and physio-biological traits. The research continues by examining the significance of panchmahabhuta and its related aspects for the whole development of human personality, including physical, mental, intellectual, social, moral, and spiritual dimensions.
