Bhagavad Gita · 2.53

श्रुतिविप्रतिपन्ना ते यदा स्थास्यति निश्चला।समाधावचला बुद्धिस्तदा योगमवाप्स्यसि॥

śhruti-vipratipannā te yadā sthāsyati niśhchalā samādhāv achalā buddhis tadā yogam avāpsyasi

When your intellect, bewildered by conflicting scriptures, stands firm and steady in the Self, then you will attain yoga.
