Periyavaa was traveling to SriSailam through a path that went through a jungle. He asked the people in his entourage to do pArAyaNa (recite) of the Vishnu Sahasranamam and walk their way.
However slowly recited, the Vishnu Sahasranamam would be over in a half hour. But then, for whatever reason, on that day, the shiSyas were not able to recite the song in unison and had to repeat the stanzas whenever a mistake was committed. The next camping site was also not in sight.
Periyavaa said, "Neither the Sahasranamam seems to end, nor the village of our destination seems to arrive."
At length they reached the village of their camping. Periyavaa said humorously, "You people did not recite Vishnu Sahasranamam. You have done a lakSArcana for Vishnu!"
The night stay was in the PerumaaL temple in that village.
A crowd of rustics from that region were waiting for the sage. They supplicated that Periyavaa should make a vijayam (visit) the temple of their village deity Katthavarayan.
Though Periyavaa was very tired, he went to the temple so the people would be happy. As he entered the temple, it started drizzling and rained heavily for an hour.
The people were flooded with happiness. Their usual experience was that if the rain clouds gathered, a powerful wind from somewhere would blow and disperse the clouds. Since Periyavaa came, the wind did not blow with the usual force, they said.
Periyavaa did not accept it. He said that as he came to the Katthavarayan temple, the deity Katthavarayan (named after the wind) stopped the wind, so it rained! -- thus giving the credit to the village deity.
An old man said, "Yes, our Katthavarayan poured out his happiness of seeing you as the rains."
