Why we are doing bhakti

it is very hard question …… why we are doing bhakti in this material world …. But we have to imagine why should do bhakti there is no point for demigods or Krishna here only point is that why we are doing bhakti?
We are doing bhakti for decreased our darkness with preach to Krishna because we are in material world means there is no benefits to anyone because we are running for our material happiness like name , fame , money like that
Like an example – if we are doing wrong work means illegal here you passed than again we will do this work for more n more time ……..because there is more return from thief any product , aapharan , murder , rape , like that from there we can get more money in few time …. Is it return?
Its not return from there we cant get anything because there is more n more problem so we should doing bhakti for decreasing our darkness …….. from leaving kalyuga…..
One think also there what is kalyuga ..?
Whatever is going now a days this is kalyuga means no one helpful , court case ,sickness , pollution, like that what is the resign behind it ? only one think is behind this we are not satisfied from any sources any work …. it is real kalyuga no one can change this only our hurt can change this material world if we will conscious for our life than we can change this era ……
We don’t know …………… who are we ??????????
We are a body nothing else raju, ashu, tasu like that we are only body for doing bhakti but we are using this body in personal matter means our bodies ….. we want to take happiness from every type of sources for our bodies ……. If we are not consciousness for krishna bhakti that’s why it is real “ kayuga”
