There might be certain limited imperfect default condition and function in the selfless physical body on top of the many conditional and influential factors that affect the impermanent condition and function of the selfless thinking faculty, but the selfless thinking faculty can overcome or transcend the limited impermanent imperfect condition and function of itself, not to say, to be overcoming or transcending the limited impermanent imperfect condition and function of the selfless physical body, if the selfless thinking faculty is free from the idea of 'I', ignorance, egoism and impurities.
Such as the selfless mind can be aware of and acknowledging the presence of the different selfless impermanent states of the mind, the ceaseless selfless thoughts, feelings or emotions arising, changing and passing away, the presence and absence of certain knowledge or skill, the different degrees of the intelligence, reasoning, cognition, attentiveness, alertness, clarity, memory and the power or speed of learning, as well as certain limitation, weakness or deficiency of certain functions due to genetic inheritance, or due to insufficient nutrients, insufficient rest, over or under sleeping, lack of good quality sleep, extremely low or excessively high energy level, physical and mental over-tiredness, over-use, over-stimulation, over-depressant, over or under activity, over or under eating, sensory or mind inputs over-loading, or due to certain illness and injury, while without egoism of attachment, identification, association, desire of craving and aversion, comparison, judgment, or expectation, knowing how to bring everything back into balance and equanimity patiently without attachment or expectation, and have peace regardless of what is the state of the impermanent condition and function of itself, not to say, the impermanent condition and function of the selfless physical body.
A lot of time, it's about decision making of whether to be performing or not performing certain action, that is determining the direction, or the transformation, or the outcome of the selfless impermanent life existence in certain way.
The mind that is free from the idea of 'I', ignorance, egoism, impurities and restlessness has no difficulty to be making the best decision at the respective timing in accordance to the condition and situation, or the possibility and impossibility in the present moment now, without attachment.
The mind that is under the influence of the idea of 'I', ignorance, egoism, impurities and restlessness, being over-powered by doubt, guilt, regret, blame, fear and worry under the absence of correct understanding, might be having difficulty of decision making, or has fear towards making decision. That's everyone's freedom for being what they are and how they are. While the mind that is in the process of eradicating the idea of 'I', ignorance, egoism, impurities and restlessness, will be over-coming or transcending even that egoistic impure condition that is also impermanent in the selfless modification of the mind, even if the mind is not completely be free from all that.
