She is resting in peace after taking Prasadam of Radha Krsna in Their pastimes in Goloka.
In fact, we can only rest in peace in Goloka, because there, we have a body without limitations and tribulations.
Resting after taking Prasadam.
Argument: "there's no sleeping in Goloka Vrindavan only 24/7 service to the Divine couple."
"Sri Rupa and the other Manjaris dedicated to Radha-Madhava's service left the Divine Couple alone and went to rest peacefully on a platform just outside the pastime abode (Lila Mandira)." (Govinda-lilamrta 23.91)
There is resting in Goloka and when they are resting and sleeping they are dreaming of more service.
Don't worry, I don't advocate the absurd idea (Fall-vadis) that we are dreaming in Goloka that we are in this material world.
