Shiva descends from Shiva to Sakala.

Agama says: Shiva(Chaitanya) itself descends from Shiva to Sakala.

Why?

Because of its own free will.

Maya is “Shivomayi”, maya is Shiva’s Veiling power but not limitation.

And then due to its own grace or revealing power, it reveals itself again, that’s why everyone who recognises the true self says I achieved nothing, just realised what already was.

Shiva is continuously performing this dance of Shrishti(emanation), Stithi(sustainance), samhara(destruction), tirodhan(concealment) and Anugraha(grace).

So everything is the grand will of Chaitanya and it is enjoying its own Leela through this play Of multiplicity and diversity.
