If you wish, [learn it from the] text (Isaiah 58:14), "Then shall you enjoy with HaShem..."; (Psalms 140:14), "...the upright shall dwell in your presence" (Psalms 16:11), "...experiencing joy is your presence..." etc, and very many others like these, are these not in all the corners of the words of the prophets and writings revealed to all the nations, seek from the texts of HaShem and read them. And in the words of our Rabbis may their memory be for a blessing (Brachos 17a), "The world to come has neither eating nor drinking...rather the righteous sit and their crowns are upon their heads, and they benefit in the splendor of HaShem's presence".
