How does tuning into nature through the sun, moon, and major planets help one's spiritual development?

Nature is nothing but a manifestation of the Ultimate reality,it is quite obvious.So tuning to nature is nothing but tuning to the God.Nature is a visible God.So tuning to it helps us in spiritual development.

I don't really tune in to nature, but admiring it and just sitting back to enjoy it does help my spiritual development by making me glorify the Creator for what He created. Only God could do such work.

Exactly!

God Bless

The fine tuning of physics undoubtedly points to a designer.

Then one may realize all of the natural miracles that God made and appreciate the the beauty of a loving God.

It doesn't unless all you are doing is admiring the creations of God; but those who are into this new-age spirituality crap

are in a very, very sad state of affairs.

They are worshipping the creation rather than the Creator.

Respect the green earth I guess.

I'm not sure. What is spiritual development?

Smoking a doobie usually helps with that!

I really don't believe that it does help one's spiritual development.

I think that comes from your beliefs, experiences, etc...

I believe that it comes from within.
