Vishal: Namaste Guru Ji, I am trying to understand since long as you said (Written below) but not able to understand till now please clarify for example how A means Virat, U means Hirnyagarbha, ma means Aditya etc. What is science behind taking these meaning why can not A stand for Hirnayagarbha, U for Virat while spelling Aum word. I hope you understood my question regarding taking different meaning for A- U -M.

Yours and Dayananad Ji explaination are
“Om has three Hindi words. Aa, Uu AND Ma. Aa is meant for Aakaar from which three names of God are built, Viraat, Agni, and Vishwadi. From Uu = uukar from which Hirannyagarbha, Vayu and Tejas names occur and Ma = makaar from which Ishwar, Aditya and Praajyan aadi, holy names of God occur.”
Swami Ram Swarup: Namskarji, aashirwad.

From aakar, uukaar and makaar not only three names of God but unlimited names are built. AUM is an eternal name of God and its names and meanings are also eternal. However answer of your question is now being a lengthy one and involves Sanskrit grammar etc. so, I would advise you to make contact with local Arya Samaj Mandir where a purohit/acharya will satisfy you personally because it requires personal sittings.

You are always welcome, beti. Neha beti, jub kabhi hum bahar jaate hain ya kisi kaam mein busy hotey hain tub bhojan karna nahi bhoolte ya der-saveir mein bhojan kar hee leitey hain. Hamein yahaan yeh samajhna hai ki Ishwar kee Pooja bhojan se bhi adhik zaroori hai. Isliye busy hokar bhi der-saver mein Ishwar ka hawan kar lena chahiye. Na karna, paap hee hoga. Kyunki manushya ka shareer Ishwar kee Pooja ke liye hee mila hai. Hawan koi bhi vastra pehan kar kiya ja sakta hai, bus shareer dhaka hona chahiye. Han! Beta, us contact number par call karne se aapko yahaan ved mandir mein aaney ka sahi—sahi rasta bataya jayega. Aapka yadi postal address hamein mil jaye to bhajan kee CD yahaan se bhej deingey.
