From listening to what the Venerable is touching on, it is a snippet on how one arrives at being a Samma Sambuddha
....that there can only be one Buddha at a time See this...

It is impossible that two rightfully Enlightened Ones should be born in the same world element at one and same time.
It is possible that a single rightfully Enlightened One should be born in the world element at one time. ...and that the next one is in Heaven waiting to be born!...is telling use there's a Heaven Again, he is sharing the processes of how one becomes the Samma Sambuddha and the causes and conditions of it...see the greater details here on how the Buddha explains it... Acchariya abbhūta Sutta

The Venerable also touched on Metteyya/Maitreya (Pali/Skt)...

"And in that time of the people with an eighty thousand-year life-span, there will arise in the world a Blessed Lord, an Arahant fully-enlightened Buddha named Metteyya, endowed with wisdom and conduct, a Well-Farer, Knower of the worlds, incomparable Trainer of men to be tamed, Teacher of gods and humans, enlightened and blessed, just as I am now. He will thoroughly know by his own super-knowledge, and proclaim, this universe with its devas and maras and Brahmas, its ascetics and Brahmins, and this generation with its princes and people, just as I do now. He will teach the Dhamma, lovely in its beginning, lovely in its middle, lovely in its ending, in the spirit and in the letter, and proclaim, just as I do now, the holy life in its fullness and purity. He will be attended by a company of thousands of monks, just as I am attended by a company of hundreds.

"Then King Sankha will re-erect the palace once built by King Maha-Panada and, having lived in it, will give it up and present it to the ascetics and Brahmins, the beggars, the wayfarers, the destitute. Then, shaving off hair and beard, he will don yellow robes and go forth from the household life into homelessness under the supreme Buddha Metteyya. Having gone forth, he will remain alone, in seclusion, ardent, eager and resolute, and before long he will have attained in this very life, by his own super-knowledge and resolution, that unequaled goal of the holy life, for the sake of which young men of good family go forth from the household life into homelessness, and will abide therein. A Theravadin commentary on the issue

The rest of the talk seems to be centered on practice as a Buddhist with mention on stuff like Noble Eightfold Path and a touch on Sotapanna, samatha & vipassana and et al.
