I recently listened to a moving Manasa Guruguha in Anandabhairavi. To hear him sing it, it's almost as if Dikshithar sings it. The composition itself is a very beautiful one. In particular, the last part of the charanam goes like this:
Nathwa Sree Guru Charanam
Kruthwa Namasmaranam Jithwa Moha varanam
Mathwa Thwadeka Sharanam
Prostrate (“nathwa”) on His feet (“guru charanam”) ;
Mediate (“kruthwa”) on His name(“namasmaranam”);
Conquer (“Jithwa”) the veil of illusion(“Moha”),
and Think (“Mathwa”) of Him as your (“thwa”) sole (“eka”) refuge (“sharanam”).
He sings those lines and proceeds to meditate on those lines. He was a person who really lived those words. I could sense the emotion in his voice when he sings those lines. Truly a great soul!!
