One and only source for the above subjects is ancient manuscripts like Scriptures and Arts irrespective of religion and rejoin.
Truth is one and there will not be more than one Truth whether east or West. language and culture and are not bars for the Truth.
The main obstacle for understanding the manuscripts is that they are full of proverbs, parables, similes, etc. Sometimes, it is called as Mystic Work which cannot be understand by ordinary people.
The mystic words are called 'Pari Pasha or Substitute'. Nowadays, the majority of people do not know that the book that is 'Pari Pasha' is also available as if a dictionary for understanding the meaning of the words. The same period when the manuscripts were written, the book of Pari Pasha was written by scholars.
