Shri Raghavendraya Namah

Chanting ‘Raghavendra” actually results in chanting the names of  Sri Rama,Hanuma and Sri Guru Raghavendra. if we describe the word Raghavendra as the most revered person in Raghuvamsha then Shri Rama is “Raghavendra” , if we describe the same word as he who has Sri Rama as his lord, then Hanuma is Raghavendra , and if describe him as the one who cleanses the sins of his devotees and protects them, then we are chanting the most renowned lord of mantrayala Shri Raghavendra. 

Sri JagannathadAsaru says:-

gururajashtaksharam syat mahapatakanashanam |

Ekaikamaksharac chatra sarvakamyartha siddhidam ||

Which means the 8 letters of “ShrI raghavendraya namah”  destroys all the mighty sins, every letter in this name, will result in fulfillment of all the wishes, 

Jagannatha dasaru also composed a separate work named “ShrI Raghavendra Ashtakshara Stotra” which describes the results of chanting each letter of SrI Rayara name as below :

Chanting of “ra” relieves one from all the diseases,

Chanting of “Ga” enhances longevity, glory and strength of the person

chanting of “va”  will result in gain of worldy riches

chanting of “dra” will drive the sins of person chanting

He who chants “ya” will not be troubled by yama

Chanting “na” will bestow higher positions

By chanting “ma” one will be blessed with riches equalling that of devendras.
