From AN 5.73 (quoted below), the Buddha advised monks to not just participate in study, description, recitation and thinking of the Dhamma, without meditation. He advised them not to neglect meditation.
Then a certain monk went to the Blessed One and, on arrival, having
bowed down to him, sat to one side. As he was sitting there he said to
the Blessed One, "'One who dwells in the Dhamma, one who dwells in the
Dhamma': thus it is said, lord. To what extent is a bhikkhu one who
dwells in the Dhamma?"
"Monk, there is the case where a monk studies the Dhamma: dialogues,
narratives of mixed prose and verse, explanations, verses, spontaneous
exclamations, quotations, birth stories, amazing events, question &
answer sessions. He spends the day in Dhamma-study. He neglects
seclusion. He doesn't commit himself to internal tranquillity of
awareness. This is called a monk who is keen on study, not one who
dwells in the Dhamma.
"Then there is the case where a monk takes the Dhamma as he has heard
& studied it and teaches it in full detail to others. He spends the
day in Dhamma-description. He neglects seclusion. He doesn't commit
himself to internal tranquillity of awareness. This is called a monk
who is keen on description, not one who dwells in the Dhamma.
"Then there is the case where a monk takes the Dhamma as he has heard
& studied it and recites it in full detail. He spends the day in
Dhamma-recitation. He neglects seclusion. He doesn't commit himself to
internal tranquillity of awareness. This is called a monk who is keen
on recitation, not one who dwells in the Dhamma.
"Then there is the case where a monk takes the Dhamma as he has heard
& studied it and thinks about it, evaluates it, and examines it with
his intellect. He spends the day in Dhamma-thinking. He neglects
seclusion. He doesn't commit himself to internal tranquillity of
awareness. This is called a monk who is keen on thinking, not one who
dwells in the Dhamma.
"Then there is the case where a monk studies the Dhamma: dialogues,
narratives of mixed prose and verse, explanations, verses, spontaneous
exclamations, quotations, birth stories, amazing events, question &
answer sessions. He doesn't spend the day in Dhamma-study. He doesn't
neglect seclusion. He commits himself to internal tranquillity of
awareness. This is called a monk who dwells in the Dhamma.
"Now, monk, I have taught you the person who is keen on study, the one
who is keen on description, the one who is keen on recitation, the one
who is keen on thinking, and the one who dwells in the Dhamma.
Whatever a teacher should do — seeking the welfare of his disciples,
out of sympathy for them — that have I done for you. Over there are
the roots of trees; over there, empty dwellings. Practice jhana, monk.
Don't be heedless. Don't later fall into regret. This is our message
to you."
In SN 9.5 (quoted below), Ven. Ananda was advised to not spend too much time informing the lay people, neglecting meditation:
Now at that time Ānanda was spending too much time informing the lay
people. Then the deity haunting that forest had compassion for Ānanda,
wanting what’s best for him. So they approached him wanting to stir
him up, and recited these verses:
“You’ve left for the jungle, the root of a tree,
with quenching in your heart.
Practice absorption, Gotama, don’t be negligent!
What is this hullabaloo to you?”
Impelled by that deity, Venerable Ānanda was struck with a sense of
urgency.
On the other hand, the Buddha did say that teaching others should not be neglected in SN 10.2 (quoted below), as it is a duty of compassion:
Then a spirit named Sakka went up to the Buddha, and addressed him in
verse:
“You’ve given up all ties,
and are fully freed.
It’s not a good idea for you, ascetic,
to be instructing others.”
Buddha:
“No matter what the apparent reason
why people are together, Sakka,
it’s unworthy for a wise person
to not think of the other with compassion.
If you instruct others
with a mind clear and confident,
your compassion and empathy
don’t create attachments.”
