In the morning, on waking, we should make the following pledge: 'Throughout the whole of today, I will remember Bodhicitta. Eating, dressing, meditating, wherever I go, I will practice it constantly. Should it slip my mind, I will remind myself. Mindful of it, I will not allow myself to wander into states of anger, desire or ignorance.' We should make a concerted effort to keep this vow and at night, before going to sleep, we should examine ourselves as to how much we have been able to generate Bodhicitta, how much we have been able to help others and whether all our actions have been in accordance with the teachings, confessing the day's faults and resolving that, from the next day onwards, within 24 hours, or a month, or at least within a year, we will have some signs of improvement. We should steel ourselves so as not to be daunted by the work of abandoning defects. If during the day our actions have not been contrary to the teachings and we have maintained an altruistic attitude, then we should be happy, thinking, 'Today has been a useful day, I have remembered what my teacher has taught me and this is to accomplish his wishes. Tomorrow I will do better than today, and even better the day after.' This is how to ensure the growth of our Bodhicitta.
