Brahmājī could understand the Lord to a little
extent only when he was trying to serve Him by
the eagerness of his heart (hṛdautkaṇṭhyavatā),
which is the devotional service mood. Therefore,
the Lord can be known only by the sincere mood
of eagerness for service, and not by any amount
of material qualification as scientist or speculative
philosopher or by attainment of mystic powers.
