No, that is not possible because a plant does not have dualistic
consciousness that suffers and give rise to dualistic, negative
emotions.
Anyway in the first place plants do not have a nervous system and
cannot react mentally to any events. Their reaction does not go
through conceptual thinking or 'mental thinking'. Just like if I
drop a molten iron ball on your hand, it is not your mind that
reacts first, but awareness and the immediate pulling away of your
hand.
As my Taiwanese teacher has often said... Awareness is your
Buddha-Nature, it is natural and spontaneous every moment.
Breathing, walking, seeing, hearing, all are happening
spontaneously as the expression of your Buddha Nature but we miss
that due to our attachment to mental constructs.
Now going back to the hand, the pulling away of the hand and the
immediate pure sensation of the pain does NOT involve dualistic
concepts and thoughts -- such as 'I am in pain'. 'I am in pain'
only comes after the pure sensation and forms due to our karmic
propensity, forming a dualistic relation 'I' and 'pain'.
The pure feeling of pain, or sound, or any perception arises first
as awareness, just that. You feel the pain first, or rather more
accurate, feeling arises first as pure awareness before you 'know'
or mentally perceive the pain. The pain is simply a spontaneous
manifestation of your own nature.
Next, it is true that any form of impure meat that is consumed has
heavier karma. It does not however mean that eating frozen meat is
totally free from karma -- it is just less because it is indirect
and not direct killing. Direct killing is more serious, that is why
I said previously in this topic,
.....Five Clean Sources of Meat (article)
...Buddha understands the
ignorance and habits of sentient beings that have accumulated from
aeons of their many past lives. In order to provide sentient beings
with an expedient means of embracing Buddhism, those who are not
able to convert to a vegetarian diet on a long term basis are
permitted to consume meat provided:
(1) That he did not slaughter the animal personally
(2) That he did not instruct others to slaughter
(3) That the slaughter was not committed for his sake
(4) That he did not witness the slaughter
(5) That he did not hear the cries associated with the
slaughter...
That is why ordered seafood is not Pure Meat. Frozen meat can at
least be considered 'clean meat' -- it is not direct killing, so
the karma is not so strong. Nevertheless it is still killing so
being vegetarian is best. But not everyone wants to be a
vegetarian, so the least is we must try eat only the 5 clean meat.
I myself try to abide by this, as I am not a vegetarian.
