Virajanand Dandeesha (Swami Virajanand), also known as the blind sage of Mathura was the celebrated teacher of Arya Samaj founder Swami Dayanand Saraswati. He was a scholar and teacher of Sanskrit grammar and Vedic literature.
Early life 
Virajanand was born in Kartarpur near Jalandhar in the year 1778 in a Brahmin family. At the age of five, he lost his eyesight from an attack of small pox. Soon thereafter, the his father who had initiated him into the rudiments of Sanskrit learning, passed away. Thus, he was thrown to the mercy of his elder brother and sister-in-law at very young age. As they did not treat him well, the temperamental Virjanand soon left their home.
His wanderings took him to Rishikesh where he led a life of meditation and austerity for about three years. Tradition has it that Swami Virjanand left Rishikesh for Hardwar at the instance of a divine command. At Hardwar, he came in contact with Swami Purnanand, a Sanskrit scholar who initiated him into 'sanyas'. Swami Purnanand created in him a deep love for Sanskrit grammar and for the "arsha" Shastras (scriptures authored by Rishis). Soon, he began to master other branches of Sanskrit literature, and also took up teaching others.
Swami Virjanand left for Varanasi (Kashi), the well-known city for Sanskrit learning and for higher studies. Here he lived for about 10 years, mastering Meemansa, Vedanta, Ayurveda, etc. Soon, he came to occupy a place of eminence among the scholars of Varanasi. From Varanasi, Swami Virjanand went to Gaya where he made a comprehensive and critical study of Upanishads continuing the work he had done at Hardwar and at Varanasi. From Gaya, Swami Virjanand went to Calcutta which was, at that time, attracting Sanskrit talent from all over the country. At Calcutta, Swamiji lived for a number of years impressing the citizens with his mastery of Sanskrit grammar and literature. In spite of the material comforts he had at Calcutta, Swami Virjanand soon left that city and settled at Gadia Ghat on the banks of the Ganges. It was here that the then Maharaja of Alwar came across the Swamiji and was greatly impressed by him. On the invitation of the Maharaja, Swamiji agreed to come to Alwar where he stayed for some time. At the request of the Maharaja, Swamiji wrote "Shabda-Bodh", the manuscript of which is still treasured in the library at Alwar. From Alwar, Virjanand went to Soron and from there to Mathura.
Pathshala in Mathura and Dayanand 
At Mathura he established a "pathshala" (school) to which students flocked from all over the country. The expenses of the pathshala were met by donations from the Rajput Princes and no fees were charged from the pupils.
Incidentally, at about the same time, Swami Dayanand Saraswati had been wandering all over the country in search of a guru. Dayanand came across a monk, Poornashrama Swamy. He heard the story of Dayanand`s wanderings and told him,"There is only one man on this earth who can fulfill your desire, and that man is Virajananda Dandeesha. He lives in Mathura." Thus, in 1860, Dayanand traveled to Mathura to meet Swami Virjanand. In their first meeting, Virjanand inquired about his objective and education. Upon learning that he had studied 'Kaumudi' and 'Saraswatha', two famous texts on Sanskrit grammar, he asked Dayanand to throw them into the river Yamuna and then come back.
Dayanand gladly surrendered himself at the feet of the great master. Swami Virjanand was a very hard task master and he expected a very high standard of diligence and discipline from his students. Even though he was blind, he could clear all doubts of his disciples, quoting verbatim passages from scriptures.
Dayanand underwent a rigorous training under Swami Virjanand. As gurudakshina, Swami Virjanand extracted a promise from Dayanand that he would devote his life for the revival of Hinduism. He would work to spread "arsha" literature and knowledge of Vedas in the country. With his extraordinary devotion and sense of service, Dayanand soon became his most beloved and also the most renowned disciple.
Death and legacy 
Swami Virjanand died on 14 September 1868, at the age of 90. Dayanand said about this loss - "Today the glorious sun of Vedic grammar has set". On 14 September 1971, the Post and Telegraph Department of India released a stamp in his honor depicting the Swamiji in a sitting posture.
