The Kālacakra is often stated to be the ‘ultimate pinnacle’ of all the tantras in various traditions, and it claims so itself.
A new post here on this website, details the reasons for that assertion given by Jetsun Tāranātha and 8th Karmapa, Mikyo Dorje. Includes exclusive, new excerpts from Tāranātha’s Kālacakra masterpiece ‘A Hundred Blazing Lights’.
“However, even compared to other Unexcelled Highest Yoga Tantras, the greatest and most supreme is the glorious Kālacakratantra; the only tantra of the ultimate, profound meaning of the vajra-yogas. It is the ‘ultimate’ or ‘pinnacle’ of all the vehicles of path and result, since it contains the results of the six branches of vajra-yoga, the ultimate pinnacle of all the vehicles of the Tripitaka teachings of the Buddha, is the glorious Kālacakratantra.”
