Bhakti-rasāmṛta-sindhu .2.258
Blended reading (Sanskrit + English inline)
This does not mean, however, that we should give up the principles of discharging devotional service or neglect abiding by the rules and regulations prescribed therein. In the neophyte stage of devotion one must follow all the principles, regulated by the authority of the spiritual master. The acceptance and rejection of things should always be in pursuance of the devotional principles; not that one can independently manufacture some idea of what should be accepted or rejected. The spiritual master as the visible manifestation of Kṛṣṇa is necessary, therefore, to direct the devotee on behalf of the Supreme Personality of Godhead.
The two verses are grammatically connected. Bhakter adhikṛtasya means “contained within the jurisdiction of bhakti scriptures.” Within vairāgya, that part which is useless (phalgu) has been rejected as an aṅga.
