In life, the tragedy is that no matter what we have, we always want more. We are rarely if ever satisfied. As intent, Santosha is doing one's best and accepting the results of one's efforts. As inner state, it is contentment that combines with and works with other virtues such as Asteya, Aparigraha and Daya (compassion for others). As outward expression, Santosha is the observed "serenity", of being “totally satisfied, not desiring anything other than the fundamental".
How often does the phrase ‘I’ll be happy when….’ Cross your mind? Santosha or 'contentment' doesn't mean idly sitting back and relinquishing the need to do anything. It simply means accepting and appreciating what we have and what we are already, and moving forwards from there. One of the most important characteristics toward which we should strive is the “attitude of gratitude”. Through gratitude we can reach contentment.
