According to Mahabharata, other scriptures and Vaishnava agamas, Lord Vishnu has his Chatur Vyuha Avatars they are Vasudeva, Samkarsana, Pradyumna, Aniruddha. Mahabharata ( Shanti Parva) says that, from Vasudeva came Samkarsana then from Samkarsana came Pradyumna and then from Pradyumna came Aniruddha. Almost like Lord Krishna's famuly tree except Lord Krishna and Lord BalaRama (as they were brothers and Lord BalaRama was the eldest one).
As for my question, I know that they ultimately meditates upon Lord Narayana (aka Para Vasudeva) only. But my real question is.:
According to scriptures does they also meditates upon their higher selfs like Aniruddha meditating upon Pradyumna or Samkarsana or Vasudeva or all 3 of them and so on for the other 3 also.???
