अर्जुन उवाच परं ब्रह्म परं धाम पवित्रं परमं भवान्।पुरुषं शाश्वतं दिव्यमादिदेवमजं विभुम् ॥

Param Brahma The highest Self. The word Param indicates the pure and attributeless Absolute, free from the limiting adjuncts. It is Satchidananda Brahman. The inferior Brahman is the Brahman with alities (Saguna) or Isvara, Brahman with the limiting adjuncts or the chosen object of meditation by the devotees.Param Dhama means Param Tejah or the supreme light. From the Creator down to the blade of grass the Supreme Being is the support or substratum. Therefore He is known as the supreme abode.Adideva The primeval God or the original God Who existed before all other gods. This God is Para Brahman Itself. It is selfluminous.Pavitram Paramam Supreme purifier. The sacred rivers and holy places of pilgrimage can remove only the sins but Para Brahman can destroy all sins and ignorance, the root cause of all sins. Therefore Para Brahman or the Supreme Self is the supreme purifier.
