“Listen
to the unsaid things
Of
the song that Radha sings
“
Gita Govinda
SB 10.21.4 "The cowherd girls began to
speak about Krishna but when they remembered His activities, O King, the power
of Cupid disturbed their minds, and thus they could not speak."
The Gopis spend their daytime speaking about Krishna.
He is in the forest and their feelings of separation churn their love while they wait anxiously for His return. Gopis' love for krishna is kept secret because of social constraints. So, in silences and in bodily expressions and in crooked discourses and puns, lovers, unmistakably, conceal messages of deep love.
Therefore the Gopis talk indirectly referring to their love for Krishna, by glorifying the birds, the clouds, peacocks, all the living entities of Vraja, who get His association. So, after long talks their voices choke in recalling His activities and beauty to their friends and love inflames their hearts. The Gopis' minds always reach out to Krishna enabling them to see Him through the love in their hearts, this makes the Gopis' love for Krishna the highest expression of Love of Godhead.
