Many claim that to advise any kind of practice is to reinforce the ego and duality, and is therefore a dualistic expression. Now there is much truth in this. However to use the same logic against itself, isn’t this in itself a duality, distinguishing between dualistic and nondualistic expressions?
Ask yourself, what is more important to you: concepts of duality/nonduality or the cessation of suffering?
Ultimately the ‘truth’, so to speak, is not to be found in concepts of any kind, and is not really truth at all but simply the end of suffering.
Many expressions can help towards this end, both so-called dualistic and nondualistic expressions. To think otherwise is to artificially restrict yourself and close yourself to the endless variety of ways life teaches and guides us home – the home we never really left – you could even say the home we always already ARE.
While there is nothing wrong with discussing teachings (it can appear to be very helpful depending on where the seeker is – although a duality is also implied in the very discussion) – to argue endlessly about conceptual teachings often implies an egotism that is attached to certain expressions (ie. teachings), and this too can be an unhealthy source of egotism and suffering.
So if you find yourself tangled up in teachings and seeking, a suggestion is to simply relax and be as you are, free from worry, free to worry.
