Lord Sri Hari Vishnu, the great savior of fallen ever remains along with devotees and followers is truth of time and ages,
Yet he has four aspects of manifestation,
Para
Apara
Vibhav
Arca
Para is the supreme one as he is in his glory, the almighty lord
Apara represents his incarnation though infinite in numbers yet could be recognised in each and every region of this universe with form and format
Vibhav is the incarnation for the cause
Arca is the descent of lord into icon ceremony installed and worshipped in the temples
And all is forms are to bless the bless that in true spirit.
Vishnu Vishnu Vishnu
May Lord bless all,
Thanks Please
