"...In the World to Come there will be no bodies and physical forms, but only the incorporeal souls of the righteous -- just like the angels of [G-d's] service. Since there will be no bodies, there will be no eating, drinking, or any of the things which human bodies require in this world. Likewise, none of the matters which are relevant to bodies in this world will be relevant to it -- such as sitting, standing, sleeping , death, sadness, laughter, and the like...And that which [the Sages] said, 'the righteous will *sit*' was metaphorical, meaning, the souls of the righteous will be found there, without work or effort. So too that which they said 'their crowns will be on their heads,' the intent is that the knowledge that they have acquired [in their lifetimes], that on account of it they merited life in the World to Come, will be with them. This is their 'crown', as the matter which Solomon said, 'with the crown which his mother crowned him' (Song of Songs 3:11)...What is [the meaning of] that which [the Sages] said, 'basking in the shine of the Divine Presence?' That they will perceive and comprehend the truth of the Holy One, blessed be He, which they cannot know while they are in a dark and lowly body..."
- Maimonides (11381204), Jewish philosopher, Torah scholar & rabbi
