Ishavasya Upanishad Bhashya in Kannada & Sanskrit PDF Format is published
IshAvAsya Upanishad belongs to Shukla Yajurveda (Vajasaneya Samhita- 14th Chapter). Other names are “YAgnEyOpanishad”, “YAgnEyamanthrOpanishad”.
Proclaimed Deity is “Sri Yagna Namaka Hari”. Swayambhu Manu is Rishi.
In nutshell it says ” Entire world is reigned by Sri Hari who is supreme, Omniscient and Omnipotent. He is the in-dweller in VAyu and all other souls. His body is AprAkrutha and as such void of all Griefs. Whatever is bestowed on us is his “Prasada” and we have to be content with only that. Never, we should beg others, for any thing else. To please him alone, we should do our duty. Attaining Wisdom and discarding illusion is a must. We should pray Almighty to bless us with Emancipation. Except Pure Bhakthi and unqualified surrender, everything fails to attain him.
