Lal says
“The deeper one comprehends the issue of suffering, the deeper the ‘Mettā’ one can generate for all beings, as Dawson pointed out.”
This sentence is very important to me. As you mentioned, Mettā is deelpy related to samsaric suffering. I thought of mettānussati in this part.
“Mettānussati is to keep in mind always that all living beings are in the same boat, suffering in the long run, and thus to have compassionate thoughts about all of them.”
Anussati and Anupassanā – Being Mindful and Removing Defilements
Thanks to you, my understanding has become clearer.
Sadhu! Sadhu! Sadhu!
