Śrīmad-Bhāgavatam · Text 11.9.31
Who is speaking and story frame
न ह्येकस्माद् गुरोर्ज्ञानं सुस्थिरं स्यात् सुपुष्कलम् ।
ब्रह्मैतदद्वितीयं वै गीयते बहुधर्षिभि: ॥ ३१ ॥
na hy ekasmād guror jñānaṁ
su-sthiraṁ syāt su-puṣkalam
brahmaitad advitīyaṁ vai
gīyate bahudharṣibhiḥ
Although the Absolute Truth is one without a second, the sages have described Him in many different ways. Therefore one may not be able to acquire very firm or complete knowledge from one spiritual master.
