So, when it comes to true happiness, only that which is for the highest good of all, will satisfy the soul. (Learn more on Finding Happiness.)
From the perspective of yoga philosophy, true fulfillment comes when we reunite our individual consciousness with the great Divine Consciousness from which we originated. This is the ultimate goal of all yoga practice. And according to the Yoga Sutras, anything less than that this will come up short in terms of feeling totally fulfilled.

With a heart devoted to love and union, whether we reach the full realization of samadhi (divine union of consciousness) in this lifetime or not, we will certainly feel fulfilled by our efforts. Thoughts and actions that align us with the qualities of the soul, such as peacefulness, truthfulness, compassion and purity, bring our human lives into balance and pave the way to ultimate fulfillment. Day by day, we can choose the path of love and trust that it will take us to the greatest happiness our hearts can hold.
