Some may say, that:
“It is difficult to apply the laws of Manu in today’s world since the conditions that exist now are very different from those when they were formally codified.”
But it’s not really true – even if some laws we may not be able to apply, due to current law system – still there are plenty of principal laws, which we can definitely apply. In Bhagavad Gita is said, that better to imperfectly do what is your duty than perfectly what is not. The same is said in Manu Samhita itself – even if you are imperfect and conditions imperfect, better is to do what is your dharma and duties.
