Note: whenever 'a' is placed before a word it gives it the opposite meaning; so here we have it before jñaana, which is knowledge – hence, ajñaana means ignorance.

jñ ~ there are several correct ways to say this. It's acceptable to pronounce it like 'gnya' or as 'jnya', or even better yet, somewhere between 'gnya' and 'jnya'.

Here, the word ends with a visarga; our next to last vowel in samshaya was an 'a', which is pronounced like a dull 'u' sound. So we kind of bounce on that once again, ever-so gently and delicately... even more so than I do...

Note: mayaa is maya / illusion.  In your pronunciation of maayaa, watch out not to make the vowel into a dipthong like 'ai'. Keep the maa clean as one sound, then the yaa clean as a second sound.

Let the 'h' be a subtle breath, so it's subtly different than a word like brama would be.
