Om shanti. Spiritual effort is the effort we make on the inside. If you have patterns of anger inside, you will be hot-headed. If you have greed, you will be unable to have a peaceful heart or to forge a connection with God. Know the deep philosophy of Karma.
Whatever your values on the inside, that will affect your speech and your interaction with others. It is the nature of human souls that your intention is clear on your face. And your intention will create your outer actions. If you keep your thoughts pure, your actions will be good and you will get blessings from God and the karmic return of those good actions.
