Prakriti means innate nature, character, physical constitution or disposition of a person. According to Ayurveda, from birth to death, doshas influence the health status and physical constitution of a man, either positively or negatively. The concentration levels and preponderance of each dosha in an individual is believed to be genetically determined. Therefore, doshas in different permutations and combinations constitute the very nature/disposition of a man. This is known as Prakriti / Sharira Prakriti.
