Fiery body (Bio-electrical (micro) body)- It is composed of the atoms of Taijasa Vargaṇā (class of material clusters qua fiery body); it is responsible for the efflugence of the body; it assists in digestion and produces the aura (bhāmaṇḍala) (which is a coloured envelope around the body); it is also responsible for attainment of Tejolabdhi (supernatural power qua energy of fiery body).

savvassa umhasiddhaṃ rasādiāhārapāgajanagaṃ ca.
teyagaladdhinimittaṃ ca teyagaṃ hoi nāyavvaṃ..
