White Tara 

The compassion that you generate for even one second, one minute, towards someone else brings you to enlightenment. Each time you generate compassion brings you closer to bodhichitta, closer to enlightenment. So even if you cannot do many other practices, keeping the mind in the thought of benefiting others makes your whole life, twenty-four hours a day, like gold, like a diamond, completely transformed. Your whole life becomes extremely meaningful, so beneficial for all sentient beings. Your life becomes the cause of happiness for all sentient beings, not just your own.
