There is a significant term in the Agamas bhavitatmabhavitatma. That person is bhavitatma who has comprehended his mind, who has objectively given a direction to his brain and the sinews to suit himself. Samskara of the sinews is very effective. There are some activities that go on only with the training of the body and the sinews. We do not have to be careful and alert in the house where we are living and where we go up and down the stairs everyday. Our feet would automatically set themselves on the steps. There will be no need to observe every second the height of the stairs. This is because of the samskara of the sinews. However, we have to be very careful while climbing an unfamiliar stair-case. We have to move our feet keeping in mind the height of the steps. Our sinews act according to the way we train them. In the case of some people, their sinews get trained in a very strange manner. In the case of some people, their fingers keep on moving. Or, even without the pen or paper, they appear in the process of writing. The sinews of one person were trained in such a manner that wherever he sat, he was always found drawing lines. Once he went for boating with his friends. But even while seated in the boat, he started drawing line in water. His friends were amazed at the way his sinews were trained.
