Are girls not allowed to sacred places during periods?

[Ms. Deepthika Venna asked:- Are girls not allowed to sacred places during periods because they give out negative energy at that time?]

Swami replied:- They are prohibited to temples during the period of menses because they are almost patients with bleeding, etc. From the point of hygiene, they are restricted and not that they are personally not eligible. When one is happy, the happiness is a form of nervous energy only. When one is unhappy, the unhappiness is also nervous energy only. The nervous energy in both is simply energy only and you cannot distinguish between these two energies like the same water present in two cups. In one cup, if you add blue colour and in another cup, if you add red colour, the colours are only different and not the water. Similarly, happiness is called positive and unhappiness is called negative. If you remove both happiness and unhappiness, you cannot say positive energy and negative energy because both are the same one energy only. You can say that you are happy or you are unhappy. As a scientist, I do not understand this positive energy and negative energy. The positive energy is with anode and the negative energy is with cathode in an electrolytic cell. Some people say that the rotation of the Rudraksha bead proves about positive and negative energies. Rudraksha bead is a part of the imaginable creation and cannot have the unimaginable power of God to indicate positive and negative energies. When these two energies are meaningless, such an experiment is also meaningless.
