Understanding the secret

Adhyaya II of the Paingala Upanishad mentions the presiding deities of the organs in the following order: Dik (the quarters), Vayu, Arka (the sun), Varuna, Aswini Devas (they are actually two, one of them being Agni), Indra, Upendra, Mrtyu (the God of death), Prajapati, the Moon, Vishnu, the four-faced Brahma and Sambhu (Siva).
Khanda V of Subala Upanishad too gives their names to be fourteen, though it is not mentioned here that they are devatas. The names are as follows: Sun, dik (the quarters), earth, Varuna, Vayu, Vak (speech), Agni, Indra, Vishnu (or Upendra), Mrtyu, Prajapati, Moon, Brahma, Rudra (name of Siva).
Isn’t it clear that the presiding deities of the organs are fourteen which include names like Varuna (water), Agni, Earth and Vayu, thereby again proving that these are not the names of elements. If Agni, Vayu, etc. are elements, then Vishnu, Brahma, Rudra, Sambhu, Indra, Prajapati, etc. too should be elements. Commentators are mostly quiet on this subject.
We have said that the 14 Masooms (Ahlebayts) have only 7 names (4 of them are named Mohammad, 4 are named Ali, 2 are named Hasan, and one each is Jafar, Musa, Husain and Fatima). It is this nomenclature and attempt to describe it in Upanishads and Vedas has often confused the scholars.
The fact that they will take birth at a ‘secret place’ too has been clearly foretold in the text from Upanishad given below. See verse II.I.8 of the Mandukya Upanishad of the Atharva-Veda:
From him come forth the seven life-breaths (seven pranas or lifes), the seven flames, their fuel, the seven oblations, these seven worlds in which move the life-breaths, seven and seven (comprising fourteen) which dwell in the secret place (secret place being the desert of Arabia).
You will see in Part-II that Vedas have shed greater light on the place they would take birth in future, and even identified the location in clear words.
