To progress in sadhana (Spiritual practice), it is necessary to have bhav (Spiritual emotion) for God. For generation of bhav, dissolution of the mind and a sattvik (Sattva-predominant) intellect are absolutely essential.
When bhav (Spiritual emotion) is awakened in a jiva, it gradually thinks more about God than itself. That is why, the existence of the self is slowly forgotten and actions as per God’s expectations are performed.
Karma (An act or action which gives rise to destiny) that we do according to our intellect or will is called the kriyaman-karma. Of the total karmas that the human beings perform, 35% are done because of kriyaman-karma.
