All beings are not only the parents in the past. They will become the Buddha in the future. If you free their lives, you are Buddha.
Gautama BuddhaWhen a man venerates those worthy of veneration, be they Buddhas or their disciples, who have transcended all obstacles and passed beyond sorrow and tears - venerating such as these, whose passions are extinguished and for whom there is no further source for fear, no one can calculate how great his merit is.
Gautama BuddhaTruths cannot be acquired from words out of other people's mouths. Before Truths can be internalized, they must come from one's own realizations and practices. Through a lifetime of personal practice, human beings are capable of revealing all of the secrets of the cosmic essence. You are your own best judge.
Gautama Buddha
