Śrīmad-Bhāgavatam · Text 11.10.5
Who is speaking and story frame
यमानभीक्ष्णं सेवेत नियमान् मत्पर: क्वचित् ।
मदभिज्ञं गुरुं शान्तमुपासीत मदात्मकम् ॥ ५ ॥
yamān abhīkṣṇaṁ seveta
niyamān mat-paraḥ kvacit
mad-abhijñaṁ guruṁ śāntam
upāsīta mad-ātmakam
One who has accepted Me as the supreme goal of life should strictly observe the scriptural injunctions forbidding sinful activities and, as far as possible, should execute the injunctions prescribing minor regulative duties such as cleanliness. Ultimately, however, one should approach a bona fide spiritual master who is full in knowledge of Me as I am, who is peaceful, and who by spiritual elevation is not different from Me.
