Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 2


तन्माधवो वेणुमुदीरयन् वृतोगोपैर्गृणद्भ‍ि: स्वयशो बलान्वित: ।पशून् पुरस्कृत्य पशव्यमाविशद्विहर्तुकाम: कुसुमाकरं वनम् ॥ २ ॥


tan mādhavo veṇum udīrayan vṛtogopair gṛṇadbhiḥ sva-yaśo balānvitaḥpaśūn puraskṛtya paśavyam āviśadvihartu-kāmaḥ kusumākaraṁ vanam


Thus desiring to enjoy pastimes, Lord Mādhava, 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 Vṛndāvana forest, which was full of flowers and rich with nourishment for the animals.


Śrīla Sanātana Gosvāmī has explained the various meanings of the word mādhava as follows: Mādhava normally indicates Kṛṣṇa to be “the Lord, who is the consort of the goddess of fortune, Lakṣmī.” This name also implies that Lord Kṛṣṇa descended in the dynasty of Madhu. Since the spring season is also known as Mādhava, it is understood that as soon as Lord Kṛṣṇa entered the Vṛndāvana forest, it automatically exhibited all the opulences of spring, becoming filled with flowers, breezes and a celestial atmosphere. Another reason Lord Kṛṣṇa is known as Mādhava is that He enjoys His pastimes in madhu, the taste of conjugal love. Lord Kṛṣṇa would loudly sound His flute as He entered the forest of Śrī Vṛndāvana, thus giving inconceivable bliss to all the residents of His hometown, Vraja-dhāma. These simple pastimes of playfully entering the forest, playing on the flute and so forth were performed daily in the spiritual land of Vṛndāvana.
