। ॥ १६७ ॥
In plain words
Without devotion to the lotus feet of Krishna, the inner self can never truly be purified. Just as a stained garment is thoroughly washed clean with alkaline water, the mind is washed clean only by love for Him.
Close to the Sanskrit
The inner self does not become clean indeed without devotion to the lotus feet of Krishna; just as a garment is washed completely by alkaline waters, the mind is cleansed by devotion.
