Paramatman and the Jiva presiding in the heart, then the Jiva does not see, smell, taste, speak, hear, feel, touch and know; when Paramatman goes out, the Chief Prana goes out after him, followed by the Lower Prana. Paramatman goes out riding on the Jiva following consciousness and work, knowledge of former life or natural capacity. In the Prashna Upanishad IV.11 the word Atman cannot refer to Jiva because the Jiva cannot of its own accord throw off its body or understand avidya, therefore, it refers to Paramatman. The Jiva attains Moksha when he actually knows the Paramatman, the Asarira Prajnatman, to be thousand-headed, to be the governor of all and to be superior to all. Thus, Paramatman is one of the many aspects of Brahman and has all attributes of Brahman. Atman (Spirit) and Paramatman (God) are one, some say they are distinct as well as one, they are one with reference to Shakti but distinct with reference to that power. Parable of the two birds The word Paramatman is not to be found in the Rig Veda but through allusion referring to Paramatman as Isha. This distinction is made because all of its mantras which in the form of prayers are addressed to gods. In its great Riddle Hymn (Sukta I.164) is the famous mantra - R.V.I.164.20, that was revealed to Rishi Deergatamaah Auchathyah and borrowed by Mundaka Upanishad III.1.1-3, which belongs to Atharva Veda, to weave the parable of the Two Birds:-Two birds. Aurobindo makes the Spirit or Purusha the Source of everything, including Brahman. He makes Purusha more fundamental. Thus, he does not have to say Brahman to be the source of inferior Brahman, and he also dismisses the sense of Reality revealed in imaginative and emotional build-up. Case of Two souls The Dualistic school of philosophy initiated by Anandatirtha draws its support from the afore-cited passage as well as from the passage of Katha Upanishad I.3.1 of an earlier Upanishad that speaks about two souls which taste the fruits of action, both of which are lodged in the recess of the human heart, and which are different from each other as light and shade, that carried the flaw—how could the Universal soul be regarded as enjoying the fruits of action? The followers of Madhva draw their support from the Bhagavad Gita XV.16 that speaks about two persons in this world, the Mutable and the Immutable;
