Four Great Vows of Bodhisattvas, First Vow
I vow to help them all.
Afflictions are inexhaustible;
I vow to end them all.
Dharma doors are boundless;
I vow to master them all.
Buddhahood is supreme;
I vow to attain it.
With much enthusiasm to learn and practice the teachings, most people start by reading books and listening to teachings by various teachers and writers. But in the vows above, we see that mastering the many Dharma doors, the different methods of learning and practice, is the third vow, not the first.
Our first step in becoming a bodhisattva is to give rise to the vow to help all beings. If we practice just to help ourselves or those we love, our mind will not be broad and spacious. It will be narrow and constricted, and our practice will be selfish.
With the first great vow, the aspiration to help all beings, our great compassion will be generated and it will compel us to be diligent on the bodhisattva path. Without this compassion and diligence, we will give up when encountering obstacles. Thus the first vow is imperative if we are to truly help others.
