have 3 observations only about the “sacrifices (Korbonot). 1. They were done off and on for 1400 years. 2. After the destruction of the 2nd Temple, they were discontinued and our Sages replaced them with prayer.
2)

3. The realization that at any time, only a small minority of our people were directly involved as participants or witnesses at any given time.

Sure, the sacrifices were always for the whole nation, whether individuals were present or not and that makes sense, as our prayers (T’filot) tend to be collective, not individual in nature and work as reminders of who we are and our relationship to Hashem and one another... 4)

rather than being requests (So really the term “prayer” is out of place in describing Jewish T’filot) 5)

But as I like controversy, this Parsha brings up the question, will sacrifices ever be restarted? And if they are restarted, since prayer was established as a substitute - maybe a better substitute as all can participate rather than just a few in Jerusalem - 6)

will the substitute be irrelevant or superfluous? And in an age of sensitivity to the idea of animal sacrifices, I doubt that they will they never be resumed.

But all those details, I think, ignore what this Parsha is really about. 7)

Sacrifices were not about pleasing G-d. Like a good parent, the being that Created us and provided us with instruction (Torah), really does not need us to work to please him.
8)

Hashem is not some narcissistic Greek god watching us and looking for an excuse to hurt us if we do not give him food and drink. 9)

Sacrifices are for us, just like prayer is for us. It is personally healthy, psychologically healthy, sociologically healthy, for people to give something of themselves, whether it is something of value that they earn... 10)

or a bit of their time put aside or a part of their attention every day, for the sake of something outside of themselves is a healthy thing. It generates thinking and contemplation and is the exact opposite of how other peoples use sacrifice... 11)

because of fear or narcissistic concerns that isolate people and detract from good mental health and the health of a society. 12)

A good argument can be made that humans, us, need something greater than us to believe in, to relate to. So, people join fan clubs, have their favorite sports teams, are patriotic to the place they live, and join ideological movements and develop religions. 13)

Christianity, Islam, and others, and we should include secular humanism as it has all the hallmarks today of a religion that excludes other religions and denounces dissent just like any other religion that demands ideological purity and conformity.
14)

And people make sacrifices for what they believe in as the price of joining

Fortunately (my opinion), Judaism is not a religion in that sense though it includes aspects of religious belief. We make sacrifices, we pray, because it is good for us.
15)

Not to beg G-d for something, not to get some key to Heaven, not to appease any leaders, not because we think it will produce magic.

So, even if you believe that there will never be sacrifices at a Temple again. It’s worth thinking about this Parsha and what it means." 16)
