maitreyaḥ uvÄca - the great sage Maitreya said; viriñcaḥ - BrahmÄ; api - also; tathÄ - in that manner; cakre - performed; divyam - celestial; vará¹£a-Å›atam - one hundred years; tapaḥ - penances; Ätmani - unto the Lord; ÄtmÄnam - his own self; ÄveÅ›ya - engaging; yathÄ Äha - as it was spoken; bhagavÄn - the Personality of Godhead; ajaḥ - the unborn.
That BrahmÄ engaged himself for the Personality of Godhead, NÄrÄyaṇa, means that he engaged himself in the service of the Lord; that is the highest penance one can perform for any number of years. There is no retirement from such service, which is eternal and ever encouraging.
