Having known David for one year, I wish to summarize the influences of David's teachings. I'm full of gratitude, and there is a desire to tell everyone how lovely David is. I'm a little concerned about being inaccurate, since these experiences are abstract and might change over time. Furthermore, I have to express myself in a language which is not my spoken one.
To phrase it briefly - the influence of David in my life is huge, almost unspeakable. I'm in the spiritual process for about 15 years, and this year was extremely intensive.

These are the main changes:

Devotional love : I didn't understand what devotion is before meeting David. I loved all my former teachers but never felt devoted to anyone in particular. I did not choose to be devoted, it just happend, originating from my heart, as a beautiful gift. No checklists were involved here, no mind. Devotion is also love, love of divinity. So actually, the spiritual process, which was a "heavy" Nyanna-Yoga path, was colored with "tsunamis" of intoxicating love and bliss. This heavenly love is similar to falling in love, but there is no destination or object, you just have to bear these intensive beautiful energies without symbolizing them or projecting thoughts to the future. Once you taste Bhakti, you can never give up this element of realization.

Faith : This was the first year I've been feeling an absolute confidence about the spiritual path. Over the years I have suffered from frequent spiritual despairs, which were always accompanied by the feeling that I'm doing something wrong. Even though I had my worst DNOS (dark night of the soul) during this year, I still had a full faith in David (and in life itself). I did not initiate the feeling of faith, it happend by itself, with the exposure to David's light. I'm not worried when there is a lack of ability to remember my Self. As David uses to say, you need to transcend both ups and downs.

Deepening of Self Inquiry : The most profound breakthrough in this practice, which became my only practice at some point, happend after the first satsang with David. It became clear to me that there is a strong connection between Shakti and realizing the true Self. During the satsang, the energies flew up to my head rapidly, opening the higher chakras. After the satsang was over, I was lying in bed, and then felt as if the individual has melted into the ocean. More accurately, I felt as if I was the ocean itself, and there was no point of reference to be called an individual. It was a big grace, and I suppose, a hint to what realization is. After a few hours the "me" was back. There were other breakthroughs during this year, which would be hard to describe, but the important thing is that there was a certain leap in the process of Self Inquiry.

Harmony in worldy life : Life became more easy, blissful and harmonious. There is a deep sense of connection to life. As David said, the Shakti helps to fulfill desires. One good example that I have mentioned before is the desire to meet David in person, which is likely to be fulfilled soon. I also feel a big change regarding social experiences. In my wordly life I have experienced a severe oppression by society, based on being a part of minority. This situation created a wall between me and other human beings (at least in my subjective experience). It had an advantage too - I saw the hypocrisy of the human society very clearly, and it encouraged me to seek for truth, as well as to identify my own fakes and unhonesty . However, this year I have experienced significant feelings of forgiveness. I understand that it is ignorance, the natural consequence of acting out of inertia, and not any structured evil in human beings. There is an experience of love towards human beings, and adoring the human diversity, which is divine. There is a decrease in judging. I find myself deeply excited from any expression of intimacy between human beings.

Divinity is merged into life : During the spiritual process, and specially after two years of Self Inquiry, I began to feel that the being itself has changed. There was less separation between meditation and daily life. After meeting David, this feeling became very prominent. I feel as if I am half human and half non-human. Knowing that your source lies in the unmanifested results in less involvement in life. There is an ego and different kind of feelings, but these are shallow, they can touch you only up to a certain level. Another result of this recognition is that life became fearless (how can one be fearful knowingly that no object can harm your being?). There are also frequent supernatural phenomena such as non-random coincidences and deep intuition. Some relate these phenomena to the opening of the third eye chakra.
