BG 11.45 -46 by HG Shyamsundar Prabhu

BG 11.45: After seeing this universal form, which I have never seen before, I am gladdened, but at the same time my mind is disturbed with fear. Therefore please bestow Your grace upon me and reveal again Your form as the Personality of Godhead, O Lord of lords, O abode of the universe.

BG 11.46: O universal form, O thousand-armed Lord, I wish to see You in Your four-armed form, with helmeted head and with club, wheel, conch and lotus flower in Your hands. I long to see You in that form.

So here Arjuna is helping our progress in understanding the personality of Godheads various forms. He has unlimited incarnations. Brahmaji in Brahma samhita says you have various forms - Rama, Narasimha...etc.He actually has multiple forms. The human form is material, because it is part of this material universe which is coming from the supreme Lord. but it is separated from him and he is not covered by it. 

People who are less advanced and are in that mode, it is advised that they  meditate on the universal form. But for devotees who want to achieve the highest position, they are advised to meditate on the two handed form of Krsna. The 4 handed Narayan forms of the lord is on each vaikunta planet. On top of all these planets - Goloka Vrindavan is Krsna residing in his original form. The reason of the Universal form is to instill fear in the hearts of the material creations. Why? because till we have fear we can't submit to the supreme Lord. Ex - if the child going to school is afraid of the consequences of not studying then he puts his energy in studying.

Only with sufficient amount of fear of the material energy can we actually submit to Krsna and try to become his pure devotee. Ex - Prabhupada said once that I'm praying to Krsna that protect me from maya, because I'm very afraid of it. Even the great acarya, GauraKishore das babaji even though very elevated, he was very afraid of maya. He would run away to the forest, because he was afraid that if I associate with materialistic people, they will take away my time from Bhakti and I will come into maya. He would go to a place with stool so there are less people disturbing him. 

Even Mahaprabhu expressed this fear example of the king wanting to meet him and Mahaprabhu rejected it. Even Sukhadeva gosvami in the womb of the mother understood maya and that maya can delude anybody and hence he didn't even come to this world and it might make him fall down. Hence we was in the womb of his mother for 17 YEARS before coming out. Universal form instills fear and by that fear we become attracted to Krsna. Same here, Arjuna is praying to Krsna I want to look at your 2 handed form. From Krsna all the lamps are being lit and then you can tell the difference between the original and the Krsna. Hence, Arjuna pleads with krsna to come to this form and it the source of all other forms and it reciprocates with all the qualities with the devotee. 

One step backwards from Krsna is Mahaprabhu. How? because he is Radha Krsna The beginning of the world is that form and to expands the pleasure of (Krsna) Radha is separate as the internal potency to give more pleasure to Krsna.

Hence he is coming as one as Mahaprabhu (combination of Radha and Krsna) and hence he is most magnanimous, generous of all the forms and he appeared to give the holy name to everybody. The most imp pasttimes of Mahaprabhu is how to become part of the Vaishnava seva whicis acutally the fact tto become a servant of the devotees how? He used to pesonally serve the devotees of the Lord. He also demoonstrated Vaishanava rules. He demonstrated the power of bhakti through his devotees. He empowered them to go out of the world and give the holy name to everybody mercilessly.  Hence read the CC, Caitanya Bhagavat and Caitanya _____

Unless and until a devotee gets the mercy of the Lord himself we can't understand this philosophy. Ex - Sarvabhuma bhatacharya gets the mercy of Mahaprabhu to listen to the vedic scriptures. Channa avatara. Mahaprabhu was asked to be a fool and chant the holy name continuously. Hence we should approach the lord and beg for his mercy because he has come to deliver everybody to the supreme Lord just  by chanting the holy name of the Lord. 

Arjuna wanted to bring us gradually from the Universal form to the 2 handed form so for the layman there is no room left for any speculation. He showed the universal form and the same Krsna shows the 4 handed form and then he comes to the Original form of 2 handed form so there is no speculation for any laymen. 

To preach we should learn from Caitanya Mahaprabhu. He shows how humble he is and actually pays his obeisances to Keshava Kasmiri and it is so nice to see how he preaches to him without humilating him. This is the way we should adopt to preach. Also, how he spoke to Prakasananda misra. about mayavadi philosophy and how humble he was.
