The different Sevas performed to the Lord are described in brief here. The devotees can choose from these services. They can reserve for Sevas by contacting the Arjhitam officer of Tirumala Tirupati Devastanam. These Sevas are normally performed when no general functions are happening on that particular day. To avoid heavy rush, as devotees would want to perform the Seva on auspicious days and Fridays, it is always advisable to reserve for the Seva 3 to 4 months in advance.
