Here is a teaching by Master Chingche on the importance of Cultivating Bodhicitta in Buddha Recitation.
Here's the translation:
When you generate the bodhicitta mind, in each recitation of the Buddha's name, besides your own liberation and renunciation, if at the moment of reciting the Buddha's name, you plant the seeds of compassion for all sentient beings, and plant the seeds of the merit of Buddhahood and aspiration in each recitation of the Buddha's name.
This recitation of the Buddha's name is inconceivable! Truly inconceivable! In the future, its help to you will not just be limited to guiding you to rebirth in the Pure Land, it has infinite energy accompanying you.
Actually, with just a little effort, you can create a better Buddha-recitation practice, you really can! You must expand your mind, place immeasurable sentient beings into this recitation of the Buddha's name, place the supreme merit of all Buddhas into this recitation, and then also place your own liberation within this recitation - then your Buddha-recitation will be perfect and complete.
This recitation of the Buddha's name, this merit of Immeasurable Light and Immeasurable Life, will continue to operate in your life until you attain Buddhahood. So you must pay attention to what you cultivate in the causal ground!
Namo Amituofo!
