The 'secret' to a fulfilled life
The 'secret' to a plentiful life, a life of harmony, happiness and contentment is to have a sattvic mind and to live in every moment in conscious contact with our true Self (Consciousness).
Whenever we have felt plenitude or a higher happiness (peace-bliss) it has been because, albeit unintentionally, we have come in contact with our true Self (Consciousness) which shines as the silent presence at the center of our existence.
