"You are the supreme primal objective. You are the ultimate resting place of all this universe. You are inexhaustible, and You are the oldest. You are the maintainer of the eternal religion, the Personality of Godhead. This is my opinion."
This is one of the slokas with larger syllables [trushtup chandas]. Upanishads eulogise the Lord. He is Avyaya [inexhaustible]; He is aksharam [indestrutible]; He is anadhi [without a beginning]; He is veditavya [ realizable by Vedas]; He is sanathana [ Ancient]; He is Purusha [Paramatman]; etc. Arjuna says thet he was able to see those praises, in person. So far Arjuna has been listening to various attributes of the Lord found in Upanishads and in Gita. Now, for the First time Arjuna was able to 'see' those attributes Himself. Once we see and store it in our mind we can never forget them. Earlier, Arjuna believed on the various statements of the Lord and now those beliefs are confirmed to him. Tvam = You [Sri Krishna] are, paramam = supreme, aksharam = never diminishable, veditavyam = realized only by Vedas. Our body as also all objects diminish over time. But the Lord has no such diminishing [either in image or in qualities]. Dve vidye vedidavye - by Two skills [learning], we can meditate and realize, Aksharam paramam narayanam - indiminishable Supreme Sriman Narayana. Arjuna is able to see this attribute of the Lord. Tvam = You [Sri Krishna] are, asya visvasya = this Universe's, param = supreme, nidhanam [निधानं] = support [ஆதாரம்]. The Lord sustains this Universe. Entire Universe is dependent on Him. Univers is a fraction of His body. Tvam = You [Sri Krishna] are, avyaya = always present or inexhausible, sasvata = permanent, dharma = righteousness, gopta = protector. The Lord ensures the protection of permanent dharma in this Universe. He himself is Dharma. In this Kshetram, Thiruvekkha, we can see beautiful Sri Rama. Valmiki says ramao vigrahavan dharma: - Sri Rama is the embodiment of Dharma. Sometimes Dharma is threatenes by evil factors. At those times the Lord takes Avatars like Sri Rama or Sri Krishna and ensures Dharma is well protected. Krishnam dharmam sanathanam - Sri Krishna is the ancient dharma. In fact in Chapter 4, the Lord said in sloka paritranaya sadhoonam....dharma samstapi...Sri Krishna appeares to establish Dharma. At that time Arjuna merely listened to the words of the Lord and now in Chapter 11, he is able to see that in real. That is he is now realizing those words. Tvam = You [Sri Krishna] are, sanatana = always present, purusha =Person, mato me = I [Arjuna have] realized by seeing. Universe is totally established in Him and Universe is sustained by the Lord. Everybody is supported by an atman. But all atman are supported by Prana or the Lord. Thus He is the basic adharam [ஆதாரம் आधारं] for entire Universe. Viswaroopam is so mammoth, that it looks like a long bridge or sethu linking this Universe and Sri Vaikuntam.
