Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My Lord, as the supreme directing Deity known as Aniruddha, You are the master of the senses and the mind. I therefore offer my obeisances unto You again and again. You are known as Ananta as well as Sankarsana because of Your ability to destroy the whole creation by the blazing fire from Your mouth.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Hrsikesendriyatmane. The mind is the director of the senses, and Lord Aniruddha is the director of the mind. In order to execute devotional service, one has to fix his mind on the lotus feet of Krsna; therefore Lord Siva prays to the controller of the mind, Lord Aniruddha, to be pleased to help him engage his mind on the lotus feet of the Lord. It is stated in Bhagavad-gita (9.34), man-mana bhava mad-bhakto mad-yaji mam namaskuru. The mind has to be engaged in meditation on the lotus feet of the Lord in order to execute devotional service. It is also stated in Bhagavad-gita (15.15), mattah smrtir jñanam apohanam ca: from the Lord come remembrance, knowledge and forgetfulness. Thus if Lord Aniruddha is pleased, He can help the mind engage in the service of the Lord. It is also indicated in this verse that Lord Aniruddha is the sun-god by virtue of His expansions. Since the predominating deity of the sun is an expansion of Lord Aniruddha, Lord Siva also prays to the sun-god in this verse.
Lord Krsna, by His quadruple expansion — Vasudeva, Sankarsana, Pradyumna and Aniruddha — is the Lord of psychic action, namely thinking, feeling, willing and acting. Lord Siva prays to Lord Aniruddha as the sun-god, who is the controlling deity of the external material elements which constitute the construction of the material body. According to Srila Visvanatha Cakravarti Thakura, the word paramahamsa is also another name for the sun-god. The sun-god is addressed herein as nibhrtatmane, which indicates that he always maintains the various planets by manipulating the rainfall. The sun-god evaporates water from the seas and oceans and then forms the water into clouds and distributes it over land. When there is sufficient rainfall grains are produced, and these grains maintain living entities in each and every planet. The sun-god is also addressed herein as purna, or complete, because the rays emanating from the sun have no end. For millions and millions of years since the creation of this universe, the sun-god has been supplying heat and light without diminution. The word paramahamsa is applied to persons who are completely cleansed. When there is sufficient sunshine, the mind remains clear and transparent — in other words, the sun-god helps the mind of the living entity to become situated on the platform of paramahamsa. Thus Lord Siva prays to Aniruddha to be kind upon him so that his mind will always be in the perfect state of cleanliness and will be engaged in the devotional service of the Lord. Just as fire sterilizes all unclean things, the sun-god also keeps everything sterilized, especially dirty things within the mind, thus enabling one to attain elevation to the platform of spiritual understanding.
