I am a Sikh by birth and also by choice, having read many scriptures. Although I consider gurbani as my sole and soul guide, I am also pretty impressed by vedantic philosophy and upanishads, which in my understanding are very close to philosophy of Sri Guru Granth Sahib.
We Sikhs believe in Parbrahm whom we call waheguru or Akaal purakh (timeless being). Gurbani also says that Parbrahm = Allah = Waheguru, and is known in gurbani by many adjective names like Karunakar (merciful), Deen dayal (merciful to poor), Bhagat vachhal (protector of his devotees), Raheem (merciful), Rehman, Kareem, and so on.
I also got to know that Hindu brothers also worship one god in many forms, but is it really so in practical life?
Because whenever I ask a vaishnav he says Vishnu ji is supreme most (parbrahm), if I ask a shaiva, he says Shivji is supreme most.
But I never saw a hindu who directly worships parbrahm (via meditation on name). Why is a deity always required? Be it Sri Ram, Sri Krishna, gods, and goddesses.
No offense intended. I am just wondering what hindu brothers think of parbrahm, because gurbani calls it the only adorable worthy of worshipping and utter dedication. And calls it alone Hari, Raam (pervading), Narayan (abode of all creatures), Nirankar, Madhava, and so on.
