Hi Raj,
Yes, those 2 are good ones.
I listen to all of the sermons, some of the more than once. All of them are good. But for starting I can suggest these: Drop the telescope get the microscope, Retaliation, Man’s pursuit of happiness, The four noble truths, Forgive and forget, Altruism, Is your mind a prostitute. And any sermons that have meditation in the title are also great.
What I like about these sermons is the Thero gives lots of examples from day to day life that I can easily relate to.
The old sermons are on Dharmayai Obai channel, link to the playlist
Hope this helps. Wish you all the best!
