It is good to be moved by the sufferings of others, but it does not mean that you get so flushed with emotion that it shakes your very being. You have to make yourself emotionally strong. Don’t let the unhappiness and miseries of others accumulate within. If you come across an affected person, express your sympathies and try to help him, but you don’t have to go out looking for unhappy people and keep getting worked up.
Every person in the world enjoys the fruits of good and evil deeds as per his prarabdha karma. Prarabdha is a part of sanchita or accumulated karma that have to be compulsorily experienced in every birth, whatever may be the spiritual credentials of the jivatman. Nobody can come to your rescue.
If you still want to be unhappy, then be so with yourself — ‘till when will happiness and sorrow continue to affect me?’ If the miseries of others affects you so much, how will you handle your own problems? Your effort should not be to simply rise above sorrows, but to rise above both happiness and sorrows, whether they are yours or someone else’s. If you continue to grieve all the time, when will you experience love and happiness?
For purity of consciousness, you must have compassion for all beings. Otherwise, there are chances that your ego may grow so big that you may start enjoying the sufferings of others. Compassion should be a part of your spiritual practice. It is not necessary that you have to do something for someone. Don’t let emotions clutter your mind. Showing compassion is good, but it is not right to be overcome with grief while showing compassion. This way, you will never experience the emotions of friendship and happiness.
