TRANSLATION

If, however, you think that the soul [or the symptoms of life] is always born and dies forever, you still have no reason to lament, O mighty-armed.

atha cainam, if however, nitya-jatam, the soul is always born, nityam va manyase mritam, then it is always destroyed tathapi tvam maha-baho, therefor even then O Arjuna

nainam socitum arhasi, so the same point is repeated the conclusion is that don’t lament don’t do Shoka.

Here, Sri Krishna is discussing the atheistic reductionist philosophy that claims life begins with chemical composition at the time of birth and ends due to chemical deterioration. This school of thought reduces life to a mere set of biochemicals that exist for a period and then die. Such an understanding of life as merely biochemicals is still present and promoted in the name of science, but it lacks both scientific and philosophical basis.

Science has not been able to create or produce life from biochemicals, although there have been experiments claiming to produce artificial life. Upon closer examination, these experiments involve the manipulation of existing life rather than the creation of life itself. Such experiments undertaken by spin doctors who employ spin doctrines—by labelling the project as “Artificial life created”—to attract funds for research and to gain prestige. In reality, the researchers of such projects; replicate DNA from an existing setup, make modifications to it, and then claim to have created new (artificial) life.

An analogy given by a prominent biologist in his book “Music of Life” illustrates this concept. Just as a sound track is not the origin of music but rather a medium for its expression, the body is considered the medium through which consciousness is expressed. Altering the genetics of certain microscopic organisms may result in different growth patterns, but consciousness is not inherent in the biochemical arrangement itself, just as music is not originated in the sound track; instead it origins from the singer. Similarly, the biochemical structure, like DNA, is produced by nature and can be modified to bring about variations in life expression, but the origin of life itself remains unanswered.

The idea that life arises solely from chemicals lacks a scientific and philosophical basis. Grand claims about creating life from chemicals may be made by media experts and spin doctors seeking attention and publicity. Sri Krishna advises Arjuna not to lament even if he encounters individuals who hold such misconceptions. Srila Prabhupada states that, Krishna used the term “Maha-baho” to indicate Arjuna’s cultural background and warrior spirit, assuring him that he will not be overcome by such petty misconceptions.

In summary, the verse addresses the atheistic reductionist philosophy that reduces life to chemicals. It challenges the scientific and philosophical basis of this perspective and advises against lamenting over such misconceptions. Instead, it encourages individuals to embrace a broader understanding of life and consciousness
