The good relationship between Sathyamoorthy and Kamaraj stood as it was till the end of Sathyamoorthy. Sathyamoorthy was innocent , so Kamaraj had the responsibility of escorting him always. He never did anything without consulting Kamaraj.

In 1940 when Sathyamoorthy was offered Vice-Chancellor's post in Madras University he consulted Kamaraj whether to accept . But Kamaraj advised him not to accept the same since Civil Disobedience Movement was about to come. If he accepts the post it may spoil his political carrier. Thus Kamaraj saved him from many plots. He was a side supporter of Sathyamoorthy. Sathyamoorthy too felt Kamaraj as a sincere friend.

 Sathyamoorthy was moving only with high levels. Kamaraj made him to move in lower level volunteers too. Sathyamoorthy introduced the high level and their status to Kamaraj. Thus they helped each other.

Sathyamoorthy loved only two. One was his daughter and other Kamaraj. Kamaraj too showed his extreme love towards Sathyamoorthy.

During Avadi Congress Conference he named the place as Sathyamoorthy Nagar. When he became Chief Minister he went to Sathyamoorthy's residence and prayed before his portrait and obtained blessing's from his wife. These were the symbols of  friendship.
