Generally, I’d say, use a wall or a other helper until you are secure enough not to fall.
Why rush something you are not ready to do ? Especially on the risk of hurting yourself.
But the issue was of that of fear. That I do not know. It is you, who have the fear who must face it, identify it, and deal with it. Your personal karma has intricacies what you alone are able to know. Surely there are a few people advanced enough to shed light on this, but most of the time they will not do that exactly to respect your freedom, or, if they’d do that they would have to ask very unpleasant things from you to perform as “payment”. Not for them, but for your own self … the wisdom in you cannot be cheated. When your Self, togheter with the forces what guide karma, decides that you need certain experiences, your ego - or other’s - has very little chance to avoid them, and if you’d somehow manage to do that, in the eyes of your higher Self, this would mean a failure, so you’d sooner or later would arrive to a similar situation.
Life shows that we learn through intensive, stressful, and painful experiences, while in comfort we tend to be less conscious of our path. We should be happy for any pain, or bad situation, as most of the time it is required for us to learn. In fact, if one is greatly affected by suffering and pain, this is one of the signs that there is still much to learn.
I dare to say these things because today we have so many ways to alleviate suffering, our materialist civilization is one of comfort, and one of the reasons of the popularity of “yoga” is that it is a powerful way to escape suffering, be it physical or on other levels. Various pains and sufferings show our attachments to various levels of our existence. But learnig to become unattached is only half of the picture, this way we only avoid too much harm being done in our future.
As we are free, and noble spiritual beings, (in our Selves), we cannot accept that someone suffers as a result of our actions. In the time between death and the next birth (what is much longer than a materialist or traditionalist view might believe), we will clearly see what we have caused, a great sorrow and regret we will feel, and these feelings will make up the factors of our next incarnation. This is the law.
Now, there is grace also ! Grace does not nullifies our errors, and the harm we have done, BUT makes possible for paying them in our chosen manner. If we do something good, even if we do not do it to the persons whe have harmed (as perhaps for that we would need more time, or a future incarnation), that would count as payment, too. This is Grace.
Exactly because of this, a certain path of selfless service of others is called karma yoga. This is a safe path, and immediatly available to anyone. It does not require a young and healthy body, fitness, or high mental faculties. It is there for even the most backward, illiterate, sick and miserable human, be it the greatest sinner of the world.
Excuse me, if I have dwellt on this subject too long … but the notion of karma, reincarnation, and divine justice, I feel one cannot overemphasise this in today’s world.
