It is customary to apply tilak on the forehead after bathing. What is the secret behind it?
The body is considered to be the temple of God. Just as the divine spirit pervades the temple, so the vibrations in the hair of the body are attracted to the divine brother. The divine element in the hair follicles of the body is especially evident in the heart. -Heart, liver, brain, kidneys are healthy, only then the body remains healthy. These organs are the pillars of the temple. The spinal cord is the entrance to the temple. There are octaves at this entrance. The last of these is the Sahasradalkamal. It is in Murdhasthani. There the unmerited Lord dwells. In Bhrukuti, the virtuous Lord resides on the ajnachakra. As long as there is Mayopadhi, it is enough to worship the Saguna Lord. Therefore, the cleanliness of the temple of the body means that after bathing, the idol of the Lord, which is in the middle of the eyebrows, should be tilaked first. This tilak is a small deity. For those who do not even have time to breathe, mundane people should wear at least tilak after bathing. That is why God is worshiped. Another secret behind wearing tilak is touching the middle of the eyebrows while wearing tilak. The scripture says that this finger should be in the middle. As it is related to the middle, the vibrations flowing through this finger travel to the heart. Japas also use Madhyama. While applying tilak to the Lord who dwells in the bhrukuti, the vibrations vibrating through the third eye go to the heart and bring devotion and peace to the mind throughout the day. The practical reason for wearing tilak is that the person wearing tilak (naming) is usually not prone to sinful deeds. Because he is one of those who believe in the existence of God. Such a person also has a different view of society. Another secular reason is that wearing Tilak is a feature of Hindu Dharma. People of any religion other than Hindus do not wear Tilak. Those who are proud of pro-Hinduism and Aryan culture must wear Tilak after bathing. Applying tila on the forehead is not just an adjective of Vedic religion, but a strong scientific principle behind it.Kathopanishad says,
Out of the hundred pulses of the heart, a pulse named Sushumna comes out from the front of the head. It is through this pulse that the path of upward salvation begins. All other nerves extend in all four directions after aspiration. The path of Sushumna, however, is only upwards. The hollow line through which the upper part of the spinal cord can be clearly seen is clearly visible on everyone’s forehead. Different tilaks are applied on the forehead according to the respective sects by centering the Sushumna Nadis. A kind of chemical process takes place when sandalwood paste is applied on the spinal cord. One of the two pulses flowing through the nose is positive and the other is negative. Sandalwood on the forehead plays an important role in preventing the heat generated by the flow of electricity. Not only as a perfume, but also with many medicinal properties such as sandalwood, turmeric, ashtagandha, gulal, krishnachandan (or bukka) etc. It is not surprising that a person who wears Tilak wisely as a part of such a tool should become an authority on the path of salvation.
