Teachings regarding Veneration/Respect (as one of the traditional 10 meritorious deeds)

Feel invited or maybe even inspired to share any teachings regarding "*Apacāyana*" (Respect or Veneration). It is one of the less taught, but very basic and fundamental, meritorious deeds. Teachings within Suttas, and Dhamma talks even from 'stranger' resources, if Dhamma, are welcome (in English and/or German). They are actually difficult to find in the modern world, since they go a lot against the grain of how Dhamma was often introduced and promoted. Such are of course just of beneficial use if they had originated and forwarded in line of meritorious deeds. Atma would like to share this merits (*Pattānuppadāna*), not to speak of rejoicing with your merits . It will not be easy to fully answer this question, so it might stay without an accepted answer for a longer time. Asian dhamma talks are normally full of this matter, now here we can hardly find anything: of course from cause. In addition: Even more complicated, such teachings should be Dhamma also given in line of Dhamma. So commercial stuff and taken things (althought it will be naturally less on this topic) is not useful since it has lost the line of respect.
