Ranganayaki is not talking about the impact of human observation as normally considered with regard to Quantum theory. She is saying that human consciousness -- our opinions and attitudes and inner psychological state -- have a direct and active bearing on the life events which occur in our immediate surroundings and impact on our life. This state tallies with my own experience and is confirmed by innumerable examples from life and literature, but it cannot be proved one way or another by mere intellectual discussion. It has to be observed and tested. I site a few examples
1. After searching for months for a greater path of knowledge, a book fell off the top shelf at a bookstore which changed the entire direction of life for my wife and myself 35 years ago. The book came in response to an intense inner aspiration and was exactly what I was looking for but did not know existed.
2. In Jane Austen's Pride & Prejudice, when Elizabeth Bennet finally decides that she should have accepted Darcy's marriage proposal, he arrives the next moment after an absence of many months. World literature is replete with sudden arrivals and 'chance' meetings that reflect a person's change in attitude or consciousness.
3. When my teacher in India asked me to take a firm decision for a psychological progress, he said if I do so, either my partner would call me from California or a close friend and client from Montreal because my decision relates to a corresponding point in their own psychological make-up. Five minutes later my client called me.
4. One night I decided to change my attitude about my co-author whose behavior I had deeply resent for various reasons. The next morning, I received the first message from him in at least one month in which he offered me a large consulting assignment, which marked the beginning of a new career.
Many similar examples are listed on the link Ranganayaki gave in her post.
