Bilal "Truth is sought for its own sake"

There are 3 parts from this video, taken from Umar the Series, MBC Production.
The first part - how the Quraish is impressed by the Bilal's mind although he is just a slave - a slave with a mind (the right idealogy) is more dangerous than a slave with a spear (technology).
The second part is the conversation between him and Wahsyi (another slave), although both are slaves to Quraish's tribe, but Bilal is a seeker and a thinker. This is why he sometimes dissappear to go and learn about the revelation from Muhammad.
The 3rd and last part is about Bilal telling Wahsyi that truth has no conditions (imposed by man, subjective) and truth is sought for its own sake - without price or anything attached to it, like waiting for the right time, right friends or right opportunity to start learning/searching.
