It is great that even before we become enlightened or generate any lam-rim realizations we are able to offer incredible benefit to others. The person who does this is a very fortunate person and should rejoice very often.
If you know the psychological nature of your own mind, depression is spontaneously dispelled; instead of being enemies and strangers, all living beings become your friends. The narrow mind rejects; wisdom accepts. Check your own mind to see whether or not this is true.
When? At this time, while you have all the opportunities, if you do not do your best to achieve the pure, stainless path to enlightenment when will you do it? If you don't meditate, don't practise the graduated path to enlightenment, especially bodhicitta, in this life, then when? When will you practise? When will you have this realization? If, in this life, you don't achieve renunciation, bodhicitta and sunyata, as well as the two stages of tantra, when will you? When will you have these attainments? When will you become enlightened? When will you perform perfect work for sentient beings?
Each one of us is responsible for other living beings' happiness, besides our own. As a result, your loving kindness is the most wish-fulfilling thing in life, more precious than anything else in this world. That makes for a most satisfying, fulfilling life.
