Glory of Ram Naam 4

 सीतानाथ समारम्भां रामानन्दार्य मध्यमाम्। अस्मदाचार्य पर्यन्तां वन्दे श्रीगुरू परम्पराम् ।।

“नेह नानास्ति किञ्चन ।” (Katha Upanishad 2.1.11), 

The previous shruti is as — यदेवेह तदमुत्र यदमुत्र तदन्विह। मृत्योस्स मृत्युमाप्नोति य इह नानेव पश्यति। (Katha Upanishad 3.2.10 

The meaning of this is as: The Supreme Brahman that exists in this world as the soul of all beings is the same Supreme Brahman that exists as the soul of beings in other realms.

The conscious (Chetan) and unconscious (Achetan) entities' inner soul (antaryami) is not different but is one and the same, known as Brahman. Therefore, there is no distinction within Brahman, and this is the meaning of "Neha Nanasti Kinchana." 

The Supreme Reality Is One Alone: Sri Ram

राम एव परं ब्रह्म राम एव परं तपः । राम एव परं तत्त्वं श्रीरामो ब्रह्म तारकम्।।

Śrī Rāma is alone Par-Brahma, Śrī Rāma is alone highest Tapa, Śrī Rām is alone highest Tattva, He is the Tārak Brahma. (Atharvaveda Ram Rahasya Upanishad Canto 1, Shloka 6)

परं ब्रह्म परं सत्यं परं ज्ञानं परं तपः । परं बीजं परं क्षेत्रं परं कारणकारणम् ॥

Sri Rama is Supreme Brahman, Supreme Truth, Supreme Knowledge, Supreme Austerity. Supreme seed, has Supreme Abode and is Supreme cause of all causes. (-Srimad Valmiki Ramayana Sundar Kand Canto 27 Shloka 26)

इदं सत्यमिदं सत्यं सत्यमेतदिहोच्यते ॥

रामः सत्यं परं ब्रह्म रामात् किंचिन्न विद्यते । तस्माद्रामस्वरूपं हि सत्यं सत्यमिदं जगत् ॥

This is an eternal truth, this is an eternal truth, this is an eternal truth; in this matter, only the truth is said to be spoken that Sri Raghunandan is the Ultimate Truth, He is Par Brahm, there is nothing exists apart from Sri Rama. As this world is the form of Sri Rama so when He is true than this world is also true, this world is also true. (Sanathkumar Samhita Ram Stavaraj Shloka 92)

श्रीमानर्च्यः शरण्यो बहुविधविवुधैर्योगिगम्याङ्घ्रिपद्मोऽ स्पृश्यः क्लेशादिभिः सत्समुदितसुयशाः सूरिमान्यो दान्यः ।

शश्वच्छ्रीरामचन्द्रः सुमहितमहिमा साधुवेदेरशेष र्निर्मृत्युः सर्वशक्तिर्विकलुषविजरो गीर्मनोभ्यामगम्यः ।।

Sri Ram is the Supreme soul. Who is worshippable by diverse scholars, abode of refuge, whose lotus-feet are attainable by yogis (devotees of the nature of Supreme devotion), free from kleśa-s etc. (a-vidyā–“ignorance”, a-smitā– “egotism”, rāga– “desire”, dveṣa– “aversion”, and abhiniveśa– “tenacity”, of mundane existence”), glories sung by maharṣi-s, revered by learned transcendentalists, generous, whose glories are decorated by entire seers and veda-s, beyond death, almighty, free from sin and growing old, unattainable through speaches and intellects, eternal, Bhagavān ŚrīRāmacandra is the īśvara.(-Vaishnav Matabaj Bhaskar 1.9)

सेवक सेब्य भाव बिनु भव न तरिअ उरगारि। भजहु राम पद पंकज अस सिद्धांत बिचारि॥119॥

Oh Garuda ji, the arch-enemy of serpents! I am a humble servant, and my Lord (Swami) is the one I serve. Without this devotion, it is impossible to cross the ocean-like world. Reflecting on this principle, let us sing praises to the lotus feet of Lord Shri Ramachandra ji. (Srimad Ramcharitmanas 7.119)

As said in Agastya Samhita;

वेदवेद्ये परेपुंसि जाते दशरथात्मजे। वेदः प्राचेतसादासीत् साक्षाद् रामायणात्मना॥

तस्माद्रामायणं देवि! वेद एव न संशयः॥

Purport: Supreme being is known through Vedas. When that Supreme being of Vedas (Sri Ram) appears as son of Dasratha in Ayodhya, that time all Vedas manifested themselves through the mouth of sage Valmiki, the son of sage Prachetus, directly as the Ramayana. Therefore, O' Devi, there is no doubt that Sri Ramayana is Vedas ITSELF.

ॐ यो वै श्रीरामचन्द्रः स भगवान्य ॐ नमो भगवते वासुदेवाय यो महाविष्णुर्भूर्भुवः स्वस्तस्मै वै नमो नमः ॥ 44 ॥

"Om, the supremely renowned Shri Ramachandra ji, is undoubtedly the Supreme Lord. And is appropriate to offer reverence with the twelve-syllable mantra 'Om Namo Bhagavate Vasudevaya.' Mahavishnu and the three primary realms are the manifestations of Lord Shri Ram. I continuously bow to Lord Shri Ram with devotion." (-Atharvaveda Ram Uttar Tapni Upanishad 4/44)

Therefore it is said in Sudarshan Samhita that Sri Maha Vishnu is the manifestation of the auspicious qualities of Lord Sri Ram.

“राघवस्य गुणो दिव्यो महाविष्णुः स्वरुपवान।”

When the infinite auspicious divine qualities of Lord Sri Ram manifests than it becomes Lord Maha-Vishnu. (-Narad Panchratra Sudarshan Samhita 1)

That is why wherever “Maha-Vishnu” word has been used for Lord Shri Ram it is actually used as a Visheshan or Adjective to show the divine qualities of Lord Sri Rama.

यस्यांशेन एव ब्रह्म विष्णु महेश्वरा अपि जाता महाविष्णुर्य्यस्य दिव्यगुणाश्च ।

स एव कार्यकारणयोः परः परमपुरुषो रामो दाशरथिर्वभुव॥

Lord Brahma, Lord Vishnu, and Lord Mahesh (Shiva) manifest from the mere fraction of Lord Shri Ram. His divine qualities are manifested in the form of Lord Mahavishnu. Lord Shri Ram, who is beyond both Karan Brahma and Karya Brahma, the Param Purusha of Vedas is the son of King Dasharatha (Atharvaveda Vedasaar Upaniṣad Uttarakhand)

Therefore originally Lord Shri Ram cannot be anyone's incarnation however verses are found which shows that Lord Shri Ram to be the manifestation of Sri Vishnu but that is only a Leela of Lord Sri Raghunandan. As in some kalp Lord Vishnu manifest as Sri Rama to spread the glory of his name and fame but in Shwet Varah kalp Lord Shri Ram himself appears who is the Lord of Saket;

अन्यकल्पेषु ह देवाः क्षीरशायी हरिः स्वयम् । रामो ज्ञेयस्तथा शेषो रुद्ररूस्स लक्ष्मणः ॥

सीता भगवती लक्ष्मीजांता जनकनन्दिनी । सुदर्शनश्च भरतो हरेः शङ्ङ्खोस्ततोऽनुजः॥

कल्पास्ये श्वेतवाराहे रामो जातः परात्परः ।

In some Kalpa, The Lord who sleeps in Sheer Sagar, Lord Vishnu manifests as Sri Ram, Sesh Naag manifests as Lakshman, Lakshmi manifests as Janak Nandini Sri Janki, Sudarshan Chakra manifests as Sri Bharata and His Shankh manifests as Sri Shatrughna but in Shwet-Varaha Kalpa Parātpar Par-Brahma Sri Ram Himself appears. (-Sri Bhavishya Puraṇa Pratisarg Khand 4 Chapter 15 Verse 60–62)

वैकुण्ठेशस्तु भरत: क्षीराब्धीशस्तु लक्ष्मणः । शत्रुघ्नस्तु स्वयंभूमा रामसेवार्थमागता: ॥

When supreme personality of the Godhead, Lord Shri Ram himself appears then his three brothers are;

Śrī Bharat who is lord of Vāikuntha (Vishnu), Śrī Lakshman who resides in Ksheer Sagar (Narayana) and Śrī Shatrughna who is swayam Bhumā Purusha (8 armed Maha Vishnu), all of them incarnated with him to serve Śrī Rāma. (-Narad Panchratra Brihd Brahma Samhitā)

Therefore Srimad Goswami Tulsidas ji said in Ramayan;

जेहि समान अतिसय नहिं कोई।

There is no one equal to Lord Shri Ram and no one is greater than him. -RCM 3.6.8

And also Shri Anantanandacharya says in his Siddhant Deepak

राम एव परं ब्रह्म तत्समोऽभ्यधिकश्च कः।

Lord Shri Ram is alone Par Brahma, Who is equal to him and who is even greater than him? -Siddhant Deepak Shlok 25,
