I have put some effort to find an answer to this question since some of the qualities of Dhamma are available in suttas. However I found very little on description on these qualities of the Buddha such as sugato, bhagavā. Since nikāya’s say that the householders should recollect these qualities as a practice it seems logical expect the detail meanings of these words. isn’t it?
Commentaries or similar kinds would be a good resource for these type of questions.
Thank you Bhante. If they are available in commentaries only then your suggestion seems reasonable.
