worshipping of a shivaling

worshipping of a shivalingam above seven cm needs to be maintained in a very
disciplined manner and on a regular basis. but for homes, i suggest a smaller
shiv lingam, specially the crystal one. no nag or heavy rituals required for
abhishekam at home. just do the abhishekam with water on six days and with
milk on mondays, place a bilva (bel) patr, if not tulsi patr, place a flower,
apply little chandan, offer incense stick, camphor and naivedyam. you can also
keep a 108 rosary made from the wood of bel tree. even though bel patr and bel
tree is liked by lord shiva, the bel patr represents goddess lakshmi and
whosoever worships bel tree or wear a rosary of bel beads, the person is
blessed with wealth. similar to tulsi beads rosaries, good quality bel beads
rosaries are also available at an affordable price of around or less than Rs.50
per mala which i supplied to many. some people also use this bel beads rosary
for chanting om namah
shivaya and other shiva mantras which are good for shiv bhakts.

only one abhishekam in the morning is required in a day. there are so many
known and unknown rules for worshipped idols for an ordinary layman which is
why i recommend worshipping the photos as the best form of worship without any
worries.
