Or reading teekas which are commentaries on lines rather than translations.
Mool Mantra
1 Sucha such na hovai
Soch, pureness; you cannot be come pure if you try 1 lakh times
You cannot loose your hunger even if you had a ton of food with you.
If you had 1 lakh smart ways of doing things and smart techniques none will go with you in the end.
So how can one get rid of falseness. By following hukam, the divine commandment, the natural way of things, the unchangeable prememt.
Hukam: the way things seems to be going.
Even if you cheat hukam the next moment it will catch up to you and correct.
