Hare krishna to all devotees.. All glories to Srila prabhupada  .

Recently i come across this following Bhagavatam sloka.  i am not able to convince my self that lord vishnu doesn't understand lord shiva's activities..

SB 8.7.31 — O Lord Girīśa, since the impersonal Brahman effulgence is transcendental to the material modes of goodness, passion and ignorance, the various directors of this material world certainly cannot appreciate it or even know where it is. It is not understandable even to Lord Brahmā, Lord Viṣṇu or the King of heaven, Mahendra.
