The State of Perfect Yoga - Bhagavad Gita Chapter2, verse53
श्रुतिविप्रतिपन्ना ते यदा स्थास्यति निश्चला |
समाधावचला बुद्धिस्तदा योगमवाप्स्यसि || 53||
shruti bi prati pannaa te yadaa sthaasyati nishchalaa
samaadhaa bachalaa buddhistadaa yogambaapsyasi
(Bhagavad Gita Ch.2, Verse53)
Your mind and intellect have become agitated and restless, by hearing too many different types of advice and instructions. When your mind and intellect will become firmly attached to God, the Supreme Soul, and will become still, you will attain Yoga. You will be forever united with God.
