Truth is something we discern from within. As we develop a relationship with our Soul, our Higher Self, we become much clearer as to what is truth for us at this time [though always being open to more learning and expanding our understanding of truth].
What we discard as truth at one particular time in our lives we may well see differently at another time.
Very often our ego discards what we hear because it brings up fear or is too different. Always be ready to think about why you are saying no to something. Writing about it in your journal can really clarify things for you.
An open mind is so important now because we are mostly so stuck in old ideas, old thinking, old ways, that no longer serve us. It’s just the pull of that comfort zone and dislike of change and difference.
An open mind and discernment and a strong relationship with your Higher Self will help you greatly to discern between ego’s dismissal and the knowing which results from your deepening connection with the inner guidance of your Higher Self.
