Only through trust, doubt can be erased

Once somebody asked Sri Swami Vishwananda following question: What about doubt- how to overcome it?

Here is his answer:
Sri Swami Vishwananda: How to overcome doubt on the spiritual path:
First, you have to trust your heart.
No- first of all, you have to trust... if you are on the spiritual path on which you have a spiritual guide, a master guiding you, you have to completely trust the Master. Secondly, you have to trust what your heart says.
But the Master will guide you to trust that.
It's only through trust, that doubt can be erased.
