The Yoga of Bhakti and Prem towards the SatGuru. 
The SatGuru is the most accessible yet the most deeply hidden One. Why? Because karma is instantaneous around Him. He hides His most tender heart very, very deeply. Because if you cause even a slight scratch upon His heart, the entirety of creation, all the energies, all the beings in every Loka will pronounce a curse upon you. Under the tremendous weight of those countless curses, your life will become hell itself for millions upon millions of years. Even Pralaya may not be able to relieve you of your suffering. You will even be robbed of the remembrance of why you are suffering. You will simply suffer endlessly. Because you have turned away from the most loving One and delivered the most abhorrent pain to Him. Hurting the SatGuru’s heart is the worst apradh ever. So He hides Himself. Not to hide from the people. Not to make Himself distant. Not to create pain for us out of separation from Him. But so that we don’t create terrible apradhs against Him and be cursed in the most horrible way. He Himself will never curse anyone. He is sweeter than Divine Nectar itself. But the atma will self-curse itself, creation will curse you, every being animate and inanimate, past, present, and future will curse you. You will not find peace anywhere not in any corner of creation. So the SatGuru hides, to stop you from living such a miserable existence because He knows that the apradhs you will create towards Him are so bad that He would rather wear the label of “far” than expose you to that hell. Can you even begin to imagine such a selfless love? No. And yet people so freely just blame the SatGuru foris absolutely unimaginable how kind the SatGuru is that He still makes Himself the most easily accessible to everyone and nullifies every curse we inherit for ourselves. He is the only one who personally makes time for each and every jeeva in the world and beyond. Do you ever see His love? Do you ever see His sweetness? Do you ever thank Him for His presence? Do you ever really make space for Him in your heart? Do you ever prioritize service to Him beyond everything else? No. Not in a single moment. Yet He pulls everyone close. Imagine the softest flower petal pulling the worst thorns towards itself. And yet the SatGuru whose heart is more tender than that and we who are much worse than thorns, we play this game all the time. Him constantly giving us the Amrit of sweetest Prem and us constantly giving Him the acid-like poison of our indifference, hatred, and doubts. 
The Yoga of Bhakti and Prem towards the SatGuru is to see the play of the atma and Paramatma in its perfection. It is to see Vaikuntha itself manifest upon earth. It is to see Him who is Everything, humble Himself to nothing in front of our atom-like remembrance of Him. To see Prem in its full divine glory one only needs to gaze upon the Lotus Feet of the SatGuru one time. This is the greatest Yoga. The Yoga, the union, of the most ungrateful jeevas with the Most Loving Being. Who other than the SatGuru would ever do this. Love for no reason. And uplift the muddiest ones upon His own sacred head. There is no other like the SatGuru. The ones who don’t leave His feet for anything or anyone in the entire Brahmand are the luckiest ones.
