Arti This is what Shri Goswami Bharatji (Pune) has to say on the subject.In Pushtimargiya Havelis Aarati is performed four times, twice in the morning session of seva and twice in the evening session. In the morning session it is performed during Mangala Darshan and during "Rajbhog Darshan. In the evening session, it is performed in Bhog-Sandhya Darshan and Shayan Darshan.
The concept is generally to ward off any evil eyes that might have fallen upon Him. While the Mangala Aarati and Sandhya Aarati is performed with the bhavana of Yashoda Maiya, who performs Aarati to ward off any evil effect of a bad dream that her Laalan may have seen in the night, or to ward off the evil eyes of any evil creatures while the Laalan was busy looking after the cows in the jungle.
The Rajbhog Aarati and Shayan Aarati is performed with the bhavana of the Gopis or Vraj Bhakt who are in the service of Swaminiji. They perform Rajbhog Arati to remove the Viraha-taap that they experienced while He was away. This is the reason why we do not take the Aarati once it is performed.
Once the taap is removed, it is not to be taken back as it is the time for Sanyog.
Only in Nathdwara, at Shrinathji the Aarati is taken because Shrinathji is Jagat-Uddharak. In Vitthalnathji too, after Rajbhog Aarati a conch full of water is waved around Shri and the water is then sprinkled over the visitors. This ritual is performed to keep the promise given to the Batuk Shastri who brought the Swaroop of Shri Vitthalnathji on the day of Gosainjis Prakatya. He had requested Shri Mahaprabhuji to let this ritual (of taking Aarati) continue on his behalf, therefore instead of taking the actual Aarati, this Sheetal Aarati is taken.
This Sheetal Aarati symbolizes the cool relief of Sanyog after the removal of Viraha Taap.
