The source of creation

The wise realise everywhere,

that which cannot be perceived and grasped,

which is without source, features, eyes and ears,

[By the higher knowledge]

The wise realise everywhere,
that which cannot be perceived and grasped,
which is without source, features, eyes and ears,
which has neither hands nor feet,
which is eternal, multiformed, all- pervasive,
extremely subtle, and undiminishing,
and which is the source of all.
