There are many people who let their Dharma practice become superficial.

It is superficial to chant the scriptures without having faith.
It is superficial to behave in an altruistic way without feeling compassion.
It is superficial to act generously without being free from stinginess.
It is superficial to be a practitioner of tantra who does not keep the commitments.
It is superficial to be a monk who does not keep the vows.
It is superficial to be noble without meditating.
It is superficial to have knowledge without practicing the Dharma.
It is superficial to engage oneself in a Dharma that does not possess the essence of practice.
It is superficial to teach others when one does not act in accordance with the Dharma oneself.
It is superficial to give advice that one does not follow oneself.

My ears are tired of listening to "'learned" people whose Dharma practice does not tame their own minds, but who simply allow it to increase their disturbing emotions. Whatever they say is nothing but superficial talk.

~ Guru Rinpoche
