As we know Tibetan Buddhism love's lists / groups of three's (among other numbers)
eg.
Three Jewels - Buddha, Dharma, Sangha
etc. etc.
Can anyone please recommend a comprehensive Buddhist lists of three?
Specifically I am looking for a group of three related to phases of being ready to teach others?
ie. Not the Three turnings of the Wheel of Dharma, but more in the context of pre-requisites for / phases of teaching others.
Possibly similar to Three trainings - Listening, Reflecting, Meditating
and how 'Realization occurs in three stages: understanding, experience, and true realization.'
I could have read it online or in a Tibetan Buddhist book eg. Any books / references by HHDL / Dilgo Khyentse / Patrul Rinpoche / Khenpo Tslutrim Gyamtso Rinpoche / Tulku Urgyen / Atisha / Padmasambhava etc. etc. ) but can't recall the exact source and have a really strong compulsion to find out, (been looking all day through books and my notes) so any pointers will be much appreciated, Thank you

BENEFITING OTHERS - Longchenpa
There are six ways in which such attainment contributes to your ability to benefit others:
Having trained in compassion, you love everyone without bias.
With consummate realization, you dissolve the confusion of believing that things have independent identity.
Familiar with the mental capacity of beings, you become skilled in the means to create auspicious circumstances.
You experience everything you perceive as an ally, free in its true nature.
Imbued with blessings, you are able to transform the: perceptions of others.
When the time is right for you to guide others, those with faith will gather around you.
Thus, all auspicious circumstances, both external and internal, will come together.
