The three main sources that I cite in articles on this blog are
Nāṉ Ār?,
Upadēśa Undiyār and
Uḷḷadu Nāṟpadu, because these are the three texts in which Bhagavan expressed the fundamental principles of his teachings in the most comprehensive, systematic, clear and coherent manner, but though there is a complete
translation of Nāṉ Ār? on my website, I have not till now given a complete translation of all the verses of either
Upadēśa Undiyār or
Uḷḷadu Nāṟpadu in one place, so since friends often write to me asking for such a translation of these texts, I have decided to give a complete translation of each of them here. Therefore in this article I give a translation of all the verses of
Upadēśa Undiyār (which Bhagavan composed first in Tamil and later translated into
Sanskrit, Telugu and Malayalam under the title
Upadēśa Sāram, ‘The Essence of Spiritual Teachings’), and in a
subsequent article I will likewise give a translation of all the verses of
Uḷḷadu Nāṟpadu.
