Canto 1 - Boyhood
Bāla-kāṇḍa
Chapter 13: Daśaratha Goes to the Sacrificial Arena
Text 1.13.39

द्रष्टुमर्हसि राजेन्द्र मनसेव विनिर्मितम्॥

draṣṭum arhasi rājendra manaseva vinirmitam

draṣṭum arhasi = O emperor; raja-indra = you should see [for yourself what has been constructed]; manasa = constructed by the mind; iva = as if; vinirmitam = it is.

O Emperor, you should see for yourself what has been constructed; it is as if constructed by the mind.

The example of the mind conveys the speed at which it has been accomplished.1

1 The mind is faster than the physical body. The preparation of the sacrificial arena was so fast that it was as if prepared by the minds of the people.
