I don't know much about the Nanaksar movement, but a brief look at the website shows photographs of Babas I have never heard of, and there seems little mention of the ten Gurus. It is a pity we do not have amongst us an expert or someone who could educate us more on this movement! If only someone could join the forum that could educate us, well I would be so happy, I would probably light a million candles!
Nanaksar is devotional sect started by baba nand singh ji around early 1900, basically back in the time trend was started due to victorian influence that people started treating sri guru granth sahib ji as mere book, would lock it up in book shelf, carry it across in bicycle etc. So to uphold devotional aspect of sri guru granth sahib ji and to restore devotional faith of people in sri guru granth sahib ji that sggs is living Guru, baba nand singh ji declared he will not eat anything until Satguru nanak dev full of attributes divine physical form appears from sri guru granth sahib ji and give him darshan and restore devotional faith of sikhs in living Guru's..days and weeks went by at the end cosmic light -Satguru nanak appeared and give discourse to baba nand singh ji that sri guru granth sahib ji is living form of all ten guru's and undivided ultimate reality. Picture of satguru nanak dev ji was also drawn by painter. So in this way, devotional sect was started to restore devotional faith of sikhs in sri guru granth sahib ji.
In a nut shell,
-They believe in amrit, they take amrit.
-They believe in all ten guru's and eleventh shabad guru
-They believe in heavily in devotional royal respect of sri guru granth sahib ji, they do akhands patt as they are told cosmic shabad resonance-gurbani should always be playing in physical royal kingdom-sachkhand.
-They believe heavily in devotional singing-kirtan, treat the place is actual royal divine kingdom(maharaj darbar sachkhand) of Guru's, and kirtan is form of devotion.
-They believe in celibacy as they are more attuned towards dedicating their life towards devotional aspect in Sikhi.
-They believe sri guru granth sahib as personal god which they have great faith in, they prayer and sing in devotion, surrender and reverence.
- They believe in their saint but more focus is on respect of sri guru granth sahib ji/guru nanak dev as their gurdwara is named after nanak-nanaksar not their saint.
-They also hold a balance between holding devotional aspect of sri guru granth sahib ji and understanding sri guru granth sahib ji as they have daily program of katha of sri guru granth sahib ji directly from faridkoti teeka(old traditional) interpretation of sri guru granth sahib ji which is also shared by other old school of thoughts- taksal, nihangs, nirmale etc.
In order to understand relationship nirgun and sargun form-devotional form of Vahiguru in sikh theology. I beleive some study on deep intertwin relationship between nirgun and sargun aspect of Vahiguru is required.
Nirguna form is not the contrast, antithesis or opposite of Saguna form of God. The same Nirguna Brahman appears as
Saguna Brahman for the
pious worship of devotees. It is the same Truth from two different points of view. Nirguna Brahman is the higher Brahman, the Brahman from the transcendental viewpoint (Paramarthika); Saguna Brahman is the lower Brahman,
the Brahman from the relative viewpoint (Vyavaharika).
