Sometimes the impressions are just general feelings. Sometimes the direction comes so clearly and so unmistakably that it can be written down like spiritual dictation.
It is through the repeated process of feeling impressions, recording them, and obeying them that one learns to depend on the direction of the Spirit more than on communication through the other five senses.
Feelings of bitterness and dissatisfaction feed upon themselves and give place to thoughts and acts of unkindness, criticism, and eventually even hatred. Criticism is often motivated by a desire to rationalize one's own shortcomings and to justify termination of sacred marriage covenants.
Chose to converse with your Father in Heaven often. Make time every day to share your thoughts and feelings with Him.
