Question about Buddhism
what I have heard in one dhammapada verse

You heard this verse wrongly. This verse says all modes of behaviour are created by mind and, when the mode of behaviour is impure, suffering follows; and when the mode of behaviour is pure, happiness follows. This Dhammapada verse is about &quot;kamma&quot; rather than &quot;solipsism&quot;.
Since Buddhism teaches suffering is caused by craving, attachment &amp; self-centredness and suffering ends when craving, attachment &amp; selfing are abandoned, whether things exist or not is not relevant to Buddhism.

If, while he is dwelling by means of this dwelling, his mind inclines to speaking, he resolves that 'I will not engage in talk that is base, vulgar, common, ignoble, unbeneficial, that does not lead to disenchantment, dispassion, cessation, calm, direct knowledge, self-awakening or Nibbana — i.e., talk about kings, robbers, &amp; ministers of state; armies, alarms, &amp; battles; food &amp; drink; clothing, furniture, garlands, &amp; scents; relatives; vehicles; villages, towns, cities, the countryside; women &amp; heroes; the gossip of the street &amp; the well; tales of the dead; tales of diversity, the creation of the world &amp; of the sea; talk of whether things exist or not.' In this way he is alert there.
