Bhakt Prahlaad was a great devotee of Lord Vishnu that faced atrocities of time and fate but never forsake the truth of devotion to the lotus feet of Lord Sri Hari Vishnu,
Holika the demonises tries to kill him once for all on this day in very diplomatic manner but Lord manifest in indifferent form to save his devotee,
Holi is a festival to mark the truth of lord Vishnu for his devotees,
Festival of Holi gradually manifest in its truth for merrymaking, announcing the commencement of the spring,, indeed a festival of colours to rejoice both ways, one needs to be wakeful and conscious on the truth of celebration of the day,
May Lord bless all
Thanks Please
