The topmost place, where love of Krsna overflows

The spiritual world is naturally superior to the material world; however,
Mathura and the adjoining areas, although appearing in the material world,
are considered superior to the spiritual world because the Supreme
Personality of Godhead Himself appeared at Mathura. The interior forests of
Vrndavana are considered superior to Mathura because of the presence of the
twelve forests (dvadasa-vana), such as Talavana, Madhuvana and Bahulavana,
which are famous for the various pastimes of the Lord. Thus the interior
Vrndavana forest is considered superior to Mathura, but superior to these
forests is the divine Govardhana Hill because Krsna lifted Govardhana Hill
like an umbrella, raising it with His lotuslike beautiful hand to protect
His associates, the denizens of Vraja, from the torrential rains sent by the
angry Indra, King of the demigods. It is also at Govardhana Hill that Krsna
tends the cows with His cowherd friends, and there also He had His
rendezvous with His most beloved Sri Radha and engaged in loving pastimes
with Her. Radha-kunda, at the foot of Govardhana, is superior to all because
it is there that love of Krsna overflows. Advanced devotees prefer to reside
at Radha-kunda because this place is the site of many memories of the
eternal loving affairs between Krsna and Radharani (rati-vilasa).
