Surya Vigyan Yogiraj Vishuddhanand Paramhansadeva was the first Yogi-Saint to introduce and propagate Surya-Vijnan, solar science, into the world for the first time. Up till then this science was confined to the ancient secrets of Gyanganj in the Himalayas in Tibet. Baba stayed in Gyanganj Ashram for 12 years. Surya i.e., Sun or Savita means source of creation. According to Surya-Vijnan there are 360 rays of the sun which go to form the whole creation of the Universe. Baba converted cot ton wool, flowers and leaves into stones, wood, etc. by the incidence of appropriate rays of the Sun. He demonstrated practically how minute particles of ingredients of various objects could be dispersed or assembled and destroyed or create d through the process of Surya-Vijnan.Production of Lord Krishna’s Fragrance through Surya-VigyanIn 1920, Shri Gopinath Kaviraj along with other disciples was sitting with Baba at the Ashram at Puri. He casually mentioned the description of Lord Krishna’s Gandha (fragrance) given in Chaitanya Charitamrit and other books and enquired if that was so in reality or it was only an allegory in the Scriptures.Baba told Gopinath Kaviraj to start naming ingredients, one by one, which formed the Krishna-Gandha, as per description given in Govind-Lilamrit. Gopinath started naming them: blue lotus, musk, etc. As each name was being pronounced, so also Shri Baba moved his hand each time in space. By the time Gopi Dada named the last ingredient, Baba brought his hand close to Gopinath and other disciples and asked them to smell the Krishna-Gandha (Lord Krishna’s fragrance). Baba told Gopinath that as he kept naming each ingredient Baba kept attracting the same out of the Sun’s rays by the process of Surya-Vijnan and by the time the last ingredient was added the fragrance was created. Gopinath and other disciples present smelled the fragrance which was marvellously sweet and enchanting.Immense Capabilities of Surya-VijnanMany disciples were direct witnesses to the creation of valuable diamonds, gems and pearls of different types and shades; ornaments of gold; sweets of various descriptions like Chamchams, Rasogullas, Sandesh etc.; fruits like grapes, pomegranates, apples and pine-apples etc; flowers like lotus, rose, jasmine, pandanus (Kevra), Parijat (a flower of paradise) etc.; cow’s ghee; coconut oil and numerous other articles, through Surya-Vijnan.
