Jai Sri Ganesha,
Time for Sri Vishnu Pad Puja but the subject is infinite in itself with subtle reality to address inherent self in truth with cause eternal,
Believing in one's own self starts the truth of this Puja which conclude with meaningful submission in faith for the lotus feet of Lord Vishnu, the savior,
At infinite locations in the sphere of time, Agamas and Puranas have relate this subtle truth time and again in scenario of life concerned with truth of respective time but core essence remains the same,
Know for Sure as time is subtle reality of truth so is truth of Lord Vishnu that subtle reality of this universe and the life, all beings are party to it, and human is blessed with special privilege to recall the truth and pastime of Lord Vishnu to charm its own reality and truth,
Jai Mahadev
