Kasu Radhakrishna Reddy was congenitally blind, yet a great exponent of music. He used to go into ecstatic state once he started chanting Amma namam. Consciously or otherwise, he used to chant and sing Amma namam in various tunes (ragas).
On one occasion, when he was all alone in the middle of night at Akhanda Namam Site, Radhakrishna Reddy started singing Amma Namam in different Carnatic and Hindustani ragas. While he was totally immersed in the ecstasy of the devotional rendering, a dog gently approached him and settled in his lap. He sensed the presence of the animal in his lap. However, he was neither disturbed nor perturbed and continued the chanting. The dog in his lap was secreting saliva from its mouth. It was so hot and almost made a burning sensation on the body of Radha annayya. Undeterred, he continued the chanting. After a while the dog joined him in chanting namam in a clear human voice! Radha annayya could perceive that the voice came from none other than the dog in his lap.
Yet, he continued his chanting and started singing in a variety of ragas changing the tempo from time to time. The dog equally matching him in his proficiency kept pace with him. This continued for quite some time.
Amma was sitting on her cot on the Southern side of the Balcony and late Sri Komaravolu Gopala Rao garu was serving Amma and keeping guard. It was almost 1.00 a.m. in the night. Amma asked Sri Gopala Rao garu, who was the other person to sing along with Radhakrishna Reddy. Gopala Rao garu, reluctant to move away from Amma, replied nonchalantly that it could be Venkateswara Reddy, the brother of Radhakrishna Reddy, since he was also a good exponent of music, thus missing the unique opportunity to watch the rare, incredible incident.
