Yes and Yes.
It is more than the sunny yellow- it is the sunny fellows and ladies that bring light to me on this forum.
There are seed exchanges. You can find people on line who will share seeds.
Territorial Seed Company has a great free seed catalog, as does Seeds of Change. They each contain information a bit over and above regular seed catalogs, and each promotes an ideology of

Wholeness???
I have some seeds I bought to share...mostly calendula right now- high in iodine, good for skin, good for thyroid. You can dry the flowers to brighten up winter soups. I already have several stamped envelopes as well. I am sorry to limit this to the US, but if anyone would like some seeds PM your snail addy to me and I will send. I should have some assorted leaf lettuces too.
Even if you grow one medicinal flower in one pot on one windowsill, that is something.
And prayer, Ke. We must always remember the prayer.
I don't know Marcus Garvey- something I plan to fix today- but I have been thinking "I'll never forget no way how they sold Marcus Garvey for rice" and I found myself praying for Marcus Garvey this morning.
It is difficult to learn to do, I must be honest that I (the I) forgets, but keep part of the brain praying constantly and God will be with you- then we are I and I and The Big I.
Is this the Kingdom of Heaven that is all around?
So now we have FIVE things to do.
1. Tithe, not to a churchy church but to God. A gift to one of God's is a gift to the self.
2. Be nice to people we don't appreciate- not for them but for our own relationship with God. That makes the I be I and I, seen?
3. Give away things of value and credit Yah with the gift. All gifts are from the Creator who also REDEEMS us. But for God we'd have naught to give.
4. Grow things. This is a BIG political self-sufficiency manuver as well. That's another post some time. Anyone?
5. Pray for others as well as ourselves. CONSTANT prayer to Jah. Dedicate part of that big brain we only use about 10% of to constant prayer.

Seen?
Feel free to change what gets by me or what I am not overstanding.
And let us add and share.
We are the revolution.
God bless.
