Buddhahood is attained through cultivation of the mind. The mind of the Buddha and that of sentient beings are no different in nature. They differ in the blessings and wisdom they contain. You shouldn't just rely on the Buddha; you should also rely on yourself, your own mind. As long as you strive to be mindful of the Buddha, your mind is that of the Buddha. Your parents can't really do anything if you don’t take responsibility for yourself. Likewise, even the Buddha can't do anything if you yourself are not willing to end the cycle of birth and death.
