SB 10.15.2
tan madhavo venum udirayan vrto
gopair grnadbhih sva-yaso balanvitah
pasun puraskrtya pasavyam avisad
vihartu-kamah kusumakaram vanam
Translation:
Thus desiring to enjoy pastimes, Lord Madhava, sounding His flute, surrounded by cowherd boys who were chanting His glories, and accompanied by Lord Baladeva, kept the cows before Him and entered the Vrndavana forest, which was full of flowers and rich with nourishment for the animals.
Purport:
Srila Sanatana Gosvami has explained the various meanings of the word madhava as follows: Madhava normally indicates Krsna to be “the Lord, who is the consort of the goddess of fortune, Laksmi.” This name also implies that Lord Krsna descended in the dynasty of Madhu. Since the spring season is also known as Madhava, it is understood that as soon as Lord Krsna entered the Vrndavana forest, it automatically exhibited all the opulences of spring, becoming filled with flowers, breezes and a celestial atmosphere. Another reason Lord Krsna is known as Madhava is that He enjoys His pastimes in madhu, the taste of conjugal love.
Lord Krsna would loudly sound His flute as He entered the forest of Sri Vrndavana, thus giving inconceivable bliss to all the residents of His hometown, Vraja-dhama. These simple pastimes of playfully entering the forest, playing on the flute and so forth were performed daily in the spiritual land of Vrndavana.
