(i) introduction:- Pancha kosha theory can be called the model of human being or the conceptualization of the human being, i.e., analysis of 5 layers. It teaches us about the mechanism of the body, mind, and spirit, from the gross elements that make up the physical body to the more subtle aspects of the mind and consciousness. “अन्नं प्राणो मनो बुद्धिर्– आनन्दश्चेति पञ्च ते । कोशास्तैरावृत्तः स्वात्मा, विस्मृत्या संसृतिं व्रजेत्” (ii) Types of Pancha kosha theory:- Annamaya kosha. Pranamaya kosha. Manomaya kosha. Vijnamaya kosha. Anandmaya kosha. (a) Annamaya kosha:- It consists of 5 elements which is known as Panch Mahabhutas namely earth, water, fire, wind and space. These five elements join together to form molecules, tissues and organs. These follow null defined lanes of nature and are controlled by nervous (electrical) and hormones (chemical). It is the mechanism to bring about movement and action in every cell. (b) Pranamaya kosha:- Prana, the vital energy is described here, it is not the material of electromagnetic energy spectrum known to modern sciences. This Prana is the basic fabric of this universe both inside and out side our body. A uniform harmonious flow of prana to each cell of the Annamaya kosha keep them alive and healthy. There are five dimensions of Prana ( Apana, Prana, Udana, Samana, Vyana). Apana:- The downward force called Apana which is responsible for urination. Prana:- It is responsible for breathing movements. Udana:- It is the upward force of the body which is responsible for upward activity like vomiting. Samana:- It is responsible for proper digestion and balancing. Vyana:- It is responsible for all activities in the periphery like nerve impulses, blood circulation and cellular activities. (c) Manomaya kosha:- It is the aspect of ones personality where the mind carries on its different functions such as memory, perception and ego (Manah, Chittah, Ahamkara). Manah - is the active part that receives sensation/impressions gathered by the five senses of cognitions/ jnanendriyas (ज्ञानेंद्रिय). Chittah- the things perceived through the five senses of cognition are stored in the chittah/memory as impressions. Hence chittah is the storehouse of karma and samskaras (impressions). Ahamkara- is a sense of 'I' ness or the faculty of identity. It claims these impressions as its own and stores them as personal knowledge or identification of ourselves with the outer world, which comes with identifying ourselves with the body – Dehatma Bhava (देहात्मा भाव)(we think we are the body). (d) Vijnamaya Kosha:- It is the 4th layer of our reality which is development in human race greatly that differentiate man from animals. We all have two minds. e.g., when the manomaya kosha said, ' It is a beautiful rose, I want to have it,' you started instructing your hand.
