After the preface , in Mahabharata proper, the thousand names start...but traditionally
in parayanam there are certain dhyanasloka which are chanted.

The ocean of milk on a glorious throne of gold adorned with dazzling jewels and pearls as resplendent as crystal gems...that sand of the ocean which is glittering like gems. And he is having shower of nectar , because of which he is in great joy...bliss...may this Narayana who is Lord Mukunda with his mace and conch which is subduing the enemy ...sanctify us ...lift us.
