Swami Pushkarini Theertham is one of the Mukkoti theerthams in Tirumala Tirupati. This is the most auspicious theertham among all seven divine tanks (Saptha theerthams). It is situated in North East side of Lord Venkateshwara temple.
It is believed as the ‘Swamini (the most auspicious) hence it is called Swami Pushkarini.
In Swami Pushkarini Theertham, Mukkoti Dwadashi (Dhanurmasa Shukla paksha Dwadashi) is considered as auspicious day to perform punya snanam (ritual bath). On this day, mukkoti (3 crores) theerthams in the Earth merge in this Pushkarini hence taking holy dip on Mukkoti Ekadashi day is highly meritorious.
In 2015, Swami Pushkarini punya kaalam falls on January 2, before Sunrise. The day before Mukkoti Dwadashi, Mukkoti Ekadashi or Vaikunta Ekadasi is observed.
This teertham was originally in Vaikuntam and belonged to Lord Sri Maha Vishnu. Garuda brought it to the Earth for Lord Venkateshwara swamy. It is adjacent to Sri Balaji temple. Devotees perform punya snanan in it before visiting the Lord.
