Swami Ramanujar's Digvijaya Yātrā

After returning from Tirupati, Swami Rāmānujar announced a Digvijaya Yātrā in which he would tour the entire country on foot, visiting multiple kshethrams. Accompanying Swami Rāmānujar on the journey were a few disciples, of whom the most prominent was Kūrattāzhvān. Swami Rāmānujar's first destination was Tirukkuṭantai. Here, he first visited the Sarangapani Perumāl Kōvil. After visiting the temple, he engaged in an intense philosophical debate with the Advaita scholars at Kumbakonam and convinced them to become Sri Vaishṇavas.

The next destination in his yatra led him to Tirumāliruñchōlai, where he visited the Kallazhagar Perumāl Kōvil. The next destination in his yatra led him to Tiruppuḷḷāṇi, where he visited the Kalyana Jagannatha Perumāl Kōvil and the Darbhashayana Rāmar Kōvil and performed the Setu Snānam.

The next destination in his yatra led him to Āzhwār Tirunāgari. The next destination in his yatra led him to Tirukkuṟuṅkuṭi. Here, Swami Rāmānujar had a conversation with Tirukkuṟuṅkuṭi Nambi. The Lord tells Bhagawad Rāmānujāchārya that he has accomplished what He could not achieve in all His births. The Lord asks to be initiated into Sri Vaishṇavism by Bhagawad Rāmānujāchārya. Bhagawad Rāmānujāchārya is said to have performed the Pancha-Samskara ceremony for the Lord here, giving Him the name Sri Vaishṇava Nambi.

The next destination in his yatra led him to Tiruvaṇparisāram, Tiruvaṭṭāṟu, and then Tiruvanantapuram. Then, traveling north, Swami Rāmānujar reached Dwārakā, where he went to see Lord Dwarkadeesh. Moving further north, Swami Rāmānujar went to Gokulam, Mathurā, Vrindavanam, and Govardhanam. Continuing north, Swami Rāmānujar visited Muktinath, Badrinath, Joshi Mutt, Devaprayāga, and then proceeded to Pushkaram.

To complete his yatra, he traveled to Kashmir in search of the Saraswati Bhandaaram, a renowned library that housed many sacred texts of Sanathana Dharma. Swami Rāmānujar, along with Kūrattāzhvān, went to the Saraswathi Bhandaaram, which was holding the Vrithi Grantham written by Bodhāyana. The Vrithi Grantham was a book that served as a commentary on all the Brahmasutrams. Swami Rāmānujar reached the Saraswathi Bhandaaram, which was being guarded by two pandits. The two pandits asked Swami Rāmānujar why he had come to the library.

When Swami Rāmānujar told them that he wanted to take the Vrithi Grantham, the two pandits laughed and guided him and Kūrattāzhvān to an idol of Devī Saraswathi. The idol posed a riddle to Swami Rāmānujar.

The riddle was as follows:" tasya yatha kapyasam pundarikam evam akshini. " Swami Rāmānujar immediately gave a detailed answer, as this was the very same statement that he had first given a commentary on under Yādava Prakashar's education. The word "kapyasam" in Sanskrit grammar has multiple meanings. One can be interpreted as the posterior of a monkey. Another interpretation is that of the thin disk of light that envelopes the sun during sunrise. Another interpretation is something that is blown up and out of proportion.

When Swami Rāmānujar provides these three explanations, he states that none of these explanations can be used to describe the eyes of the Lord. Swami Rāmānujar describes that the word kapi, in Sanskrit, refers to the sun. The word kapyasam refers to kapya: aayasam, which can be described in the following scenario. Imagine a pond filled with still freshwater, where lotus flowers bloom. When the sun's rays fall on the pond's surface, the water evaporates, causing the lotus to bloom with all its resplendence.

Thus, the eyes of the Lord can be described as equivalent to those of the sun and possess a gaze that is as soft as the petals of the lotus.

Saraswathi Devī tells Swami Rāmānujar that she was impressed by his answer and that She would grant him access to her library and allow him to take the Vrithi Grantham. Thus, Swami Rāmānujar took the Vrithi Grantham and started his journey back towards Sri Rangam. By night, Swami Rāmānujar and Kūrattāzhvān reached Kāshī and decided to spend the night there. Swami Rāmānujar fell asleep, saying he was tired from the travel.

Later in the morning, when both Swami Rāmānujar and Kūrattāzhvān awoke from their sleep, they saw that the Vrithi Grantham was missing. Swami Rāmānujar was heartbroken as he understood the pandits must have stolen the Grantham from them when they were sleeping.

Kūrattāzhvān then tells his Āchārya not to feel bad, as he had read the entire Grantham in the night before falling asleep. He told his Āchārya that his curiosity to know what was in the Grantham did not let him sleep; thus, he read every last word in the Grantham before going to sleep. Swami Rāmānujar decides to test Kūrattāzhvān and asks him to recall whatever he can remember from the Grantham. Kūrattāzhvān recited the entire Grantham before Swami Rāmānujar and told him that he could remember anything he read in a single attempt.

Swami Rāmānujar and Kūrattāzhvān returned to Sri Rangam.

After returning to Sri Rangam, Swami Rāmānujar began writing another magnum opus, a commentary on the Brahmasutras written by Bhodayana. Swami Rāmānujar used the references of Āzhwār Pāsurams, Brahmasutra-Artham, which he was taught by Tirukacchi Nambi, and the Vrithi Grantham through Kūrattāzhvān to write the great Sri Bhasyam.
