Tamāla Kṛṣṇa: Purport: "There are three degrees of covering of the pure living entity, and thereby the pure consciousness of the living entity, or Kṛṣṇa consciousness, is embarrassed by nonmanifestation. This covering is but lust under different manifestations, like smoke in the fire, dust on the mirror, and the womb about the embryo. When lust is compared to smoke, it is understood that the fire of the living spark can be a little perceived. In other words, when the living entity exhibits his Kṛṣṇa consciousness slightly, he may be likened to the fire covered by smoke. Although fire is necessary when there is smoke, there is no overt manifestation of fire in the early stage. This stage can be compared with the beginning of Kṛṣṇa consciousness. The comparison of the dust of the mirror refers to the cleansing process of the mirror of the mind by so many spiritual methods. The best process is to chant the holy names of the Lord. The comparison of the embryo being covered by the womb is an analogy illustrating the most awkward position, for the child in the womb is so helpless that it cannot even move. This stage of living condition can be compared also to the trees. The trees are living entities, but they have been put into that condition of life by such a great exhibition of lust that they are almost devoid of all consciousness."
Prabhupāda: Yes, these trees... We should know that the trees, they are also living entities, but they have been put in such awkward position that they are standing up in a position for thousands of years. They cannot move even. If somebody is cutting, it cannot protest. They have been put into such conditional life. If somebody is coming to do some harm, they cannot go away. So the most abominable condition of life is the trees. Go on.
