I have read that Sri Vishnu worships Devi Parvati and Lord Shiva.
Nama Shivaabhyam sarasothsavabhyam, Namaskruthabheeshta vara prathabhyam, Narayanenarchitha padukabhyam, Namo Nama Sankara Parvatheebhyam
Salutations to Lord Shiva and Goddess Shivaa, Whose playful love is a festival, Who grant boons to those who salute them, And whose feet is worshipped by Lord Narayana, Salutations and salutations to Lord Sankara And to that Goddess Parvathy. -Uma Maheshwar Stotram
But did Devi Parvati worship Sri Vishnu? Which Purana mentions this?
