Also you may perhaps have hundreds of friends; but when you call them before your memory you do not confuse them one with another: each one is separate and distinct, having their own individualities and characteristics.
(‘Abdu’l-Bahá, ‘Abdu’l-Bahá in London, p. 75)

Briefly, in the powers which animals and men have in common, the animal is often the more powerful. For example, let us take the power of memory: if you carry a pigeon from here to a distant country, and there set it free, it will return, for it remembers the way. Take a dog from here to the center of Asia, set him free, and he will come back here and never once lose the road. So it is with the other powers such as hearing, sight, smell, taste, and touch.
(‘Abdu’l-Bahá, Bahá’í World Faith, p. 304-305)

Consequently, it has become evident that the four criteria standards of judgment by which the human mind reaches its conclusions (senses, intellect, traditional or scriptural and inspiration) are faulty and inaccurate. All of them are liable to mistake and error in conclusions. But a statement presented to the mind, accompanied by proofs which the senses can perceive to be correct, which the faculty of reason can accept, which is in accord with traditional authority and sanctioned by the promptings of the heart, can be adjudged and relied upon as perfectly correct, for it has been proved and tested by all the standards of judgment and found to be complete. When we apply but one test, there are possibilities of mistake. This is self-evident and manifest.
(‘Abdu’l-Bahá, Promulgation of Universal Peace, p. 255)

Everyone, then, who desireth “victory” must first subdue the city of his own heart with the sword of spiritual truth and of the Word, and must protect it from remembering aught beside God: afterwards let him turn his regards towards the cities of [others‘] hearts.
(‘Abdu’l-Bahá, A Traveller’s Narrative, p. 63)

Know then: that which is in the hands of people, that which they believe, is liable to error. For, in proving or disproving a thing, if a proof is brought forward which is taken from the evidence of our senses, this method, as has become evident, is not perfect; if the proofs are intellectual, the same is true; or if they are traditional, such proofs are also not perfect. Therefore, there is no standard in the hands of people upon which we can rely. But the bounty of the Holy Spirit gives the true method of comprehension which is infallible and indubitable. This is through the help of the Holy Spirit which comes to man, and this is the condition in which certainty can alone be attained.
(‘Abdu’l-Bahá, Some Answered Questions, pp. 297-299)

Man can certainly recall past experiences in his evolution, and even when his soul leaves this world it will still remember its past.
(Shoghi Effendi, Lights of Guidance, p. 113)

Man has also spiritual powers: imagination, which conceives things; thought, which reflects upon realities; comprehension, which comprehends realities, memory, which retains whatever man imagines, thinks, and comprehends … For instance, sight is one of the outer powers; it sees and perceives this flower, and conveys this perception to the inner power—the common faculty—which transmits this perception to the power of imagination, which in its turn conceives and forms this image and transmits it to the power of thought; the power of thought reflects, and having grasped the reality, conveys it to the power of comprehension; the comprehension, when it has comprehended it, delivers the image of the object perceived to the memory, and the memory keeps it in its repository.
(‘Abdu’l-Bahá, Bahá’í World Faith, p. 317)

Man has memory and reason; nature lacks them.
(‘Abdu’l-Bahá, Bahá’í World Faith, p. 243)

Your therapist is also in the best position to assist you to distinguish between those events which have occurred, and any other impressions in your memory which may not be based on actual experiences.
