OM SAI RAM
Dear Babaschild,
Concentrate on the crux of the instruction.
That is Shiv Puja.
How and where you do it is not a problem with any God.
He doesn't care about material things you do or offer.
He is hungry for the love and devotion in your heart.
You could stand in the most crowded trains, but if you are one with HIM in that moment, then nothing else matters.
Its the addiction to God's name that's important. Not the wheres and hows, and whys.
Pray with your soul, rest leave it to Baba and Shivji.
Baba Bless All
