Blazhen tot kto is the Russian opening of a devotional phrase meaning blessed is the one who trusts only in God living in heaven. The wording echoes traditional Christian prayer and psalm language rather than a modern catchphrase, which is why the tags around the clip point to God, faith, Jesus and Christ. On TikTok and similar short video platforms it circulates as a ready to use blessing sound, shared under church clips, prayer posts and personal faith edits where the Russian singing itself carries the message even for viewers who need a translation.
