bhakthi

narada bhakthi sutra   defines bhakthi as   saa paramaprema bhakthi , yatha, vraja gopikanam. u know one must surrender unto the lord{ur ishta devatha},just as gopikas did surrender unto lord krishna at vraja bhoomi. surrender means giving up ur kartruthwam ie  doership. that i am the doer of my worldly actions instead  i take it this way. lord  is the kartha, and i  am a nimitha or an instrument. its he who makes me to do an action. and the results are also as per his orders. result may be good,bad, or even negative. i as  a jeeva, accept the results and accept  the same with prasada budhhi.. here for gopis of vraja bhoomi krishna is the jagatpathi and not their husbands. husband is only pathi. lord krishna is jagatpadhi.therefore surrendering to the supreme lord one can overcome the samsara sukha-dukkha{worldly happiness and sorrows}its the highest form of bhakthi when u forget ur mind/bodyconscienceness.its total surrender unto the lord. narada is  the highest authority of bhakthi. his suthra is called narada bhakthisutra
