umbrella

[Нюра]

Ни как не пойму о чем речь: functioning as umbrella or raison d'etre.В отдельности все переводится, а вместе не имеет смысла :(
Context: Without a doubt Pithagoras' religious-political movement provided the wherewithal for these types of pursuits(философские искания), perhaps functioning as umbrella or a raison d'etre.
Спасибо всем большое!
