The salutation above may sound like a mystery, ……

but let us delve into it a bit. The sole refuge for a seeker are the lotus feet of the Guru, and the Padukas that represent them. It is to gain freedom from Samsara that one surrenders at His feet sans a condition, for He is the only means, The Only Means.
The Guru's Feet are verily the embodiment of the Lord, as both the Mother and the Father – Father, when He teaches, and Mother, when unconditional compassion flows from Him – no wonder, the Guru's Feet are Shiva and Shakti, the only Parents of the Universe! So then, it is ..
ॐ नमः शिवाभ्यां , गुरु-चरणाभ्याम् !

Please look at every picture of abhishekam in close-up (like this one above), you will find the Guru's lotus feet right with the Lingam, inseparable!
Thus was this Shani-Mahapradosham celebrated with Rudrabhishaekam to Maheshwara, as always, so that Guru's grace flows to us, to know Him!

Darshan from in between Nandikeshwara's horns.
The next Mahapradosham occurs on Sunday, the 14th of January, 2018, which coincides with Makara-Sankranti, making it doubly auspicious!
