Yes, I agree totally in that each Guru must advise on how their own practices may be performed.
I haven't asked but I perform daily practices by LOTR and ChNN entirely separately and hours apart.
Guruyoga, however, as opportunities arise during the day.
It is an interesting point about the integration of Dzogchen into daily life, though, and what another Guru may think if we are integrating Dzogchen we have learned from ChNN when performing their sadhanas. I have no idea!
