It is indeed a very stiff admonition

If a person without  scientific and thorough learning and proper training  practices prediction through astrology, indulges in legal arguments, prescribes expiatory measures, or does treatment for diseases he should be considered   a murderer of the Brahma himself.

The sloka may appear very innocuous.  But see the realities of life.  How many amateur astrologers who have not even seen the elementary texts of astrology, are found sitting (nowadays) in the company of laptops and reeling off predictions about your past, present or future... and anything can be justified by a glib tongue especially when the audience is  impressionable ( and in this matter one finds even the most astute persons gullible), and causing havoc in the lives of others?.  The influence of such evil astrologers are very prominent especially in the marriage market..before marriage, during marriage  and when some hard luck strikes after marriage and the same is credited to the account of the poor female.

Then take the case of lawyers who are also probably liers. They promise  everything under the sun to their clients but the fat  law-books stacked for all to see  in their chambers and the journals they subscribe to are only pieces of exhibition.  When raising for argument before the honourable bench, they cannot go beyond " Your Honour.... I pray for a short adjournment".  The client's fate is doomed in their hands.

And there are the so called saints and swamis, who claim to have attained revelation and sit in the comfort of their air-conditioned parnasaalas (the holy leaf abodes)  eagerly waiting to pounce upon any victim who may come near.  They reveal very intricate truths (!) about the sins of the victim and prescribe remedies and the ultimate result is that the victim is divested of whatever wealth or good sense he has and lands up in a state of confusion (fortunately not kanfusion)  which is dished out as absolute bliss (if not for the victim, for the swamiji)

Last but not the least comes the quack.. a medical practitioner without any proper knowledge. We can meet  the animals in the market under various breeds and pedigrees, allopathy, homeopathy, aayurveda, unani,  siddha, reiki, pranic, yogic,herbal or holistic..to mention only a few.  Even the healthiest man should take very hefty insurance policies before visiting such great creatures. One's death is assured. 

Such avatars manifest in the world repeatedly.
Their  most gullible victims are young girls who get into some unwanted troubles, people who come into  possession of some secret but shameful diseases and people with more money than they can think of spending in the right way. 
 Even the Income tax man will take away your money but permit you to live,  but these quacks will rob you of your money and will not be kind enough to  spare your life.

One interesting common factor for all the above demons is that they will always have a retinue of well trained touts.

Yes, such people are capable of murdering even Brahma himself.
