In the diversity of living species, the incarnate being does not know under which form, animal or plant, it will have to be reborn. This is why it is absolutely necessary to revive our original consciousness, the Krishna consciousness, also called God consciousness.
We must remember the glories and other entertainments of God, sing the hymn of His Holy Names, and somehow we can apply ourselves to directing our thoughts to the Lord and thus achieve put in our mind with the utmost seriousness. This is how one becomes free from all fear of death.
The embodied being knows nothing of his destiny after death, because of the total domination exercised over him by the laws of material nature. Now Krishna, God, the Supreme Person, is the only Master of natural laws, so that by seriously taking refuge in Him, we will see all fear of falling again among so many species disappear.
The sincere holy being is sure to reach the abode of the Lord in his absolute and eternal kingdom.
Logos 424
Whatever material body it resides in, the spiritual soul is always the same.
As pure spirits, all spiritual souls are equal and identical, regardless of whether they reside in a body of a celestial being, of an inhabitant of the Edenic, paradisiacal planets, of a human being, of an animal or of a plant.
Therefore the Lord says: Those who are truly enlightened do not see the outward appearance of the living being, [the material body] whether it is a celestial being, an inhabitant of the paradisiacal planets, a human being, an animal or 'a vegetable.
Those who are enlightened by pure divine knowledge no longer see the body of dense matter of white, black, yellow, red, mestizo, or the animal or vegetable material form, but only the spiritual entity, the spiritual soul which is there, which resides there.
From then on they feel towards all human beings without exception an equal love. They go even further, because in all the bodies of animals and plants, they also see only the spiritual soul that resides there, and neither do they differentiate between a man, a woman, a dog, a cat, elephant or ant, they love them all with equal love.
