parita mahad-adibhih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
All the visnu-murtis were surrounded by the opulences, headed by anima-siddhi; by the mystic potencies, headed by Aja; and by the twenty-four elements for the creation of the material world, headed by the mahat-tattva.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this verse the word mahimabhih means aisvarya, or opulence. The Supreme Personality of Godhead can do whatever He likes. That is His aisvarya. No one can command Him, but He can command everyone. Sad-aisvarya-purnam. The Lord is full in six opulences. The yoga-siddhis, the perfections of yoga, such as the ability to become smaller than the smallest (anima-siddhi) or bigger than the biggest (mahima-siddhi), are present in Lord Visnu. Sad-aisvaryaih purno ya iha bhagavan (Cc. Adi 1.3). The word aja means maya, or mystic power. Everything mysterious is in full existence in Visnu.
The twenty-four elements mentioned are the five working senses (pañca-karmendriya), the five senses for obtaining knowledge (pañca-jñanendriya), the five gross material elements (panca-mahabhuta), the five sense objects (pañca-tanmatra), the mind (manas), the false ego (ahankara), the mahat-tattva, and material nature (prakrti). All twenty-four of these elements are employed for the manifestation of this material world. The mahat-tattva is divided into different subtle categories, but originally it is called the mahat-tattva.
