The meaning of this Bandish:

Sangata keenhe guniyana kee guna aave

Meaning

One acquires virtues by keeping the company of the virtuous (guniyan).
Only those who understand the true worth of the wise gain deeper insight.
True refinement comes when the mind immerses itself among the learned.
Ultimately, one should focus the mind in devotion and contemplation.

Emotion: ज्ञान + साधना + संगति का प्रभाव

Bhagavad Gita Connection - Chapter 2, Verse 64

राग-द्वेष-वियुक्तै तु विषयान् इंद्रियैष चरण
आत्मा-वश्यैर-विधेयात्मा प्रसादं अधिगच्छति ||

Through disciplined association and control, one attains clarity and peace.

परन्तु जो मन को वश में रखता है, और आसक्ति एवं घृणा से मुक्त रहता है,
वह इंद्रियों के विषयों का प्रयोग करते हुए भी ईश्वर की कृपा प्राप्त करता है।

Connection

Bandish: “संगत कीन्हे गुणियन की” → company shapes character
Gita: spiritual growth happens through association with the wise

Clear message: You become what your company is.

Insight
