A lady wishing to marry God!? This was close to a revolution in spirituality. What does it mean? Such entire episode is termed as Madhura Bhakthi (sweet devotion) where the seeker (soul) unites with God through love.
But, how did she fall in love with God? Her father (a great devotee himself, Vishnuchitthan) narrated stories of God (especially Krishna) as he brought her up. This inculcated deep love for God in her heart. Her love was so sweet and pure that God’s supremacy was neatly absorbed into it. This is the union, the wedding of her soul with God! Proving the truth in her love, God accepted her and made her available to all of us as Deity, so we can worship her for showing us a beautiful path to eternal bliss through love!
