Hayagreeva Jayanti occurs on Shravana Purnima. During year 2018 this event will occur on August 26th. Hayagreeva is one of the minor incarnations of Lord Vishnu. There is much deeper meaning and purpose to Hayagreeva: for this Kali Yuga, let it be known that Hayagreeva, when propitiated, gives very pure knowledge. He is karaka of the intellect, which resides nearest the soul (atma).
