Matsyavatara,

Jai Shani Dev,
Lord Shani, a devotee of lord sri Hari Vishnu is know to the world,

9 define incarnations of lord Vishnu is course for devotees to adore with to reach at the lotus feet of Lord,

Lord Vishnu incarnated as Matsyavatara as the first, exact reason cannot be elaborate at this moment yet ancient scripture support the fact that Lord Saved Progenitor of mankind that Manu,

And Lord saved all the seven sages for a cause, sages that mind born sons of Brahma, lord saved them along with their wives,

Indeed many reasons may be there but essence of the truth lies in mercy of Lord that he cares and is a great saviour,

Obeisance to Lord Vishnu in his Matsyavatara,

May Lord bless all,

Thanks Please
