Please understand that the formless god concept is not a very great realization. Also, the if you believe that you can address him by any name, why is name jap given so much importance? The name of the Lord is same as the Lord. And therefore chanting the name alone purifies. Any amount of heartfelt praying is not going to get you anywhere. Only names such as Krishna will penetrate deep and cleanse your soul. Please try to understand my arguments wholly by its logic.
dear nrkalee
you are a vaishnava and i respect your beleif but please don't try to impose your beleif on others that krishna is supreme god and only it makes you no different from muslims who propagate that allah is true god and onlly mohammed is the last prophet and all those who don't beleive in it will go to hell
let me show you a shabd of kabir ji
ਲਖ ਚਉਰਾਸੀਹ ਜੀਅ ਜੋਨਿ ਮਹਿ ਭ੍ਰਮਤ ਨੰਦੁ ਬਹੁ ਥਾਕੋ ਰੇ ॥
लख चउरासीह जीअ जोनि महि भ्रमत नंदु बहु थाको रे ॥
Lakẖ cẖaorāsīh jīa jon meh bẖarmaṯ nanḏ baho thāko rė.
Wandering through 8.4 million incarnations, Krishna's father Nand was totally exhausted.
ਭਗਤਿ ਹੇਤਿ ਅਵਤਾਰੁ ਲੀਓ ਹੈ ਭਾਗੁ ਬਡੋ ਬਪੁਰਾ ਕੋ ਰੇ ॥੧॥
भगति हेति अवतारु लीओ है भागु बडो बपुरा को रे ॥१॥
Bẖagaṯ hėṯ avṯār līo hai bẖāg bado bapurā ko rė. ||1||
Because of his devotion, Krishna was incarnated in his home; how great was the good fortune of this poor man! ||1||
ਤੁਮ੍ਹ੍ਹ ਜੁ ਕਹਤ ਹਉ ਨੰਦ ਕੋ ਨੰਦਨੁ ਨੰਦ ਸੁ ਨੰਦਨੁ ਕਾ ਕੋ ਰੇ ॥
तुम्ह जु कहत हउ नंद को नंदनु नंद सु नंदनु का को रे ॥
Ŧumĥ jo kahaṯ hao nanḏ ko nanḏan nanḏ so nanḏan kā ko rė.
You say that Krishna was Nand's son, but whose son was Nand himself?
ਧਰਨਿ ਅਕਾਸੁ ਦਸੋ ਦਿਸ ਨਾਹੀ ਤਬ ਇਹੁ ਨੰਦੁ ਕਹਾ ਥੋ ਰੇ ॥੧॥ ਰਹਾਉ ॥
धरनि अकासु दसो दिस नाही तब इहु नंदु कहा थो रे ॥१॥ रहाउ ॥
Ḏẖaran akās ḏaso ḏis nāhī ṯab ih nanḏ kahā tho rė. ||1|| rahāo.
When there was no earth or ether or the ten directions, where was this Nand then? ||1||Pause||
ਸੰਕਟਿ ਨਹੀ ਪਰੈ ਜੋਨਿ ਨਹੀ ਆਵੈ ਨਾਮੁ ਨਿਰੰਜਨ ਜਾ ਕੋ ਰੇ ॥
संकटि नही परै जोनि नही आवै नामु निरंजन जा को रे ॥
Sankat nahī parai jon nahī āvai nām niranjan jā ko rė.
He does not fall into misfortune, and He does not take birth; His Name is the Immaculate Lord.
ਕਬੀਰ ਕੋ ਸੁਆਮੀ ਐਸੋ ਠਾਕੁਰੁ ਜਾ ਕੈ ਮਾਈ ਨ ਬਾਪੋ ਰੇ ॥੨॥੧੯॥੭੦॥
कबीर को सुआमी ऐसो ठाकुरु जा कै माई न बापो रे ॥२॥१९॥७०॥
Kabīr ko suāmī aiso ṯẖākur jā kai māī na bāpo rė. ||2||19||70||
Kabeer's Lord is such a Lord and Master, who has no mother or father. ||2||19||70|
so worshiping of one formless god is the basic philosophy of sikhism.If you agree with it its fine if you don't then it is also fine you can worship krishna as you like but please don't try to impose your beleifs on uthers
