Shape of Sukshma Sharira is spherical and it consists of microform of five components – 1. Earth, 2. Water, 3. Air, 4. Fire, 5. Space. Jivatma and Brahm leave the heart and enter the microform of fire component and space component respectively, Senses leave the sense organs and enter microform of earth component, PRANA leaves the lungs and enters microform of air component Mana leaves the brain and enters microform of water component of Sukshma Sharira after death of Parthiv Sharira. Sukshma Sharira  is spherical shaped and its diameter equals with the size of thumb. In Sukshma Sharira microform of earth component merges in microform of water component, which merges in microform of air component to merge finally in microform of fire component. In this way in Sukshma Sharira, senses merge in Mana, which merges in Prana, which merges in Jivatma. In Sukshma Sharira, Jivatma can not merge in Brahm because microform of fire component does not merge in microform of space component. With Jivatma and Brahm, The Sukshma Sharira lives in the sky and when it enters cardiogenic area of developing embryo, pulsations start in the arterial heart.
