While watching Baba Takhur Singh, were you just looking with your worldly eyes that can only see dust or were you using your internal eyes. If you were using your internal eye you might have seen the jagdi jot inside of them. Sants are ones that have reached a manjal, not just a name.
babur and Bhai Lehna both looked at Guru Nanak, but didn't obtain the same laha; Bhai Lehna became Guru Angad Dev and babur put Guru Nanak in jail.
