Ādi-līlā, Chapter 1

Personality of Godhead's acting as the spiritual master from within. He was the spiritual master who instructed Brahmā, the original living being in the cosmic creation. When Brahmā was first created, he could not apply his creative energy to arrange the cosmic situation. At first there was only sound, vibrating the word  tapa , which indicates the acceptance of hardships for spiritual realization. Refraining from sensual enjoyment, one should voluntarily accept all sorts of difficulty for spiritual realization. This is called  tapasya . An enjoyer of the senses can never realize God, godliness or the science of theistic knowledge. Thus when Brahmā, initiated by Śrī Kṛṣṇa by the sound vibration  tapa , engaged himself in acts of austerity, by the pleasure of Viṣṇu he was able to visualize the transcendental world, Śrī Vaikuṇṭha, through transcendental realization. Modern science can communicate using material discoveries such as radio, television and computers, but the science invoked by the austerities of Śrī Brahmā, the original father of mankind, was still more subtle. In time, material scientists may also know how we can communicate with the Vaikuṇṭha world. Lord Brahmā inquired about the potency of the Supreme Lord, and the Personality of Godhead answered his inquiry in the following six consecutive statements. These instructions, which are reproduced in the  Śrīmad-Bhāgavatam  (2.9.31-36), were imparted by the Personality of Godhead, acting as the supreme spiritual master.
