The Vedic scripture presents an evolution of spiritual thought towards God. It evolves from the lower stages of fear to duty conscious to love towards a Transcendent Being. Depending on our nature, there are different religious principles available to follow. If, however, we want to know and love God in all His glory then we have to follow in the footsteps of bonafide authority.
A bonafide spiritual authority is one who has submissively heard from his own spiritual master and is submissively following what his spiritual master has instructed. This lineage of teacher-student should start directly from God. Anything not this, in the strict sense cannot be considered bonafide.
Today, however, there are so many believers who do not follow any bonafide authority and hence dogmatic and sentimental. The atheistic class emerge against these dogmatism and sentimentalism. Unfortunately people see both dogmatism and fervent/genuine spiritual theology as one. But if we choose to submit to a proper authority as indicated above and submissively follow the authority, rest assured we will understand the mysteries of universal spiritual values.
