What is so Esoteric about Spiritual Texts?

   Most of the spiritual Texts go back to origin of 'Silence' and 'Sound' emerging out of it! There is the secret of creation in every GAP (sandhi) between sound and sound. The alphabet (alpha and beta) of the 'Sound of Breath' of Devi Sharada, the Deity of Knowledge, Who breathes unto others without Herself breathing. This gives us the Bijakshara, the seed letters that create the mantrakshara (potent letters) and the mantra which are powerful enough to create the material world. How can one write or understand these abstract things, that involve the very creation?  The absolute abstract is the source of all creation, the Brahmn.
   Thus, the term sa ukta', 'thus spake the Lord' comes. This Bhagavan Uvacha, as stated in the Bhagavad-Gita is a most important esoteric aspect; it says, "Arjuna, I shall relate to you the most secret of the secrets"- guhyatama guhyamam pravashyaami | 

   In the first instance, the spiritual texts of Agama Shastra like the Narada samhita, sanaka, skandha, sanatsujata and other samhita (shastra, almost 200 of them) are believed to be older than the Veda.no a are divine laws codified by the learned sages as dictated by the very Devi Devata. Normally, we do not understand what is that the Lord says, when they say, 'Bhagavan Uvacha' as in the Bhagavad-Gita. We have to understand the words of the Lord as heard by his devotee Arjuna, or as narrated by the Learned Amatya Sanjeeva to King Dhrutarashtra, or as dictated by Veda Vyasa to Lord Ganapati. Actually, these are spiritual aspects, very abstract, and not coming within the grasp of uninitiated students. In fact, there is neither a Veda Vyasa (Veda and Vyasa means radius and circumference meaning wholeness or entirety?) since it is the pen-name or attribute to Shree Krishna Dvaipayana, nor there is a Ganapati, who is the deity of muladhara prajnya, basal plexus? When they say that the Veda is an unwritten script,many Rks heard in samadhi state (Transcendental Meditative state) we cannot understand. However, these are now written down in words that do not match the original spirit of the text.Many words like The Atman, jivatman,paramatman, Prana, Prajnya, life-breath and the nerves and neurons cannot be properly described. The source of all that is called 'anthahkarana'- the mind, the intellect, the ego, are all beyond physical domain. When does spirit turn into matter and whether gross matter can be turned into spirit are the eternal questions. The texts we read or hear are not what they appear to be, and there is more for that. That is the esoteric aspect of the ancient spiritual scripts. The Shakta and the tantra shastras are the most mystic ones. The practices are not at all rational and scientific, at the outset. But, one cannot deny the fact that there are terrific forces operating behind these tantra, mantra and yantra?
