Dear Inder Pal Singh Ji,
The language you had used in your post indicates that you are very sure of your understanding. I pray to 'The Sat' that such frame of mind I never get, it will hamper my progress, all my life I want to remain a learner.

I have spent part of my life learnig of ancient scripture of our land. All the terms you have referred in your post, I new them all. If vedas were to be the guideing principle of Sikhi, ther was no need for Guru Sahibs to invest ten lives to help us transform to Sikhi. Even Upnishads which evolved after vedas do not agree completely agree with vedas and at places are critical of them. I do not wan to relapce into the ancient past of our land. You appear to be familiar with vedas. In vedas the devetas were, indra, surya etc etc; there is no Devi in Vedas. You know in Upanishad they became Shiva, Bhrama and Vishnu. Further down it became that all are One. Tantras brought it concept of Devi, Yoga and kundalini. Finally vedvyasa wrote Bagvatam, if you are familiar with the ancient scripture of our time I am sure you must be knowing why did vedvyas compile this last Granth. After this Mahabharat (which includes Gita) and Ramayana was written. I think you must be knowing why Mahabharat was compiles and why is it called MAHAbharat; Dr Sarvapalli Radhakrishann, former president of India has explained it in his book Philosophy of India.
I am not for mystifying the simple Sikh religion by bring the complications from other religion through back door (through explanations). Those concepts which our Guru Sahibs have left behind, I do not want to pick them up. Once we bring some these concepts in Sikhi others too will follow on their own and Sikhi will not remain what Guru Sahib gave us. Sihki is an independent religion and does not need support from concepts from other religions.

I do not want to pass any Judgement, but request you not to spend time for me, I will continue to evolve at a pace in accordance with the Hukam of 'The Sat'.
Observations I will always read but may not respond unless there is something in it for me to learn. This is for the simple reason, as with all of us, I too have 24 hours in a day. this aplies to all the post, no matter who has posted.
With love and respect for all
Amarpal Singh
