Rishi Markandya had professed that Kaliyug would see the downfall of dharma. All the gyan will be lost and people will criticize the Vedas. Pious sciences of Yoga and Tantra will be misrepresented and sold for private gains. Well, the Kaliyug he described is here...
The science of Tantra, our great Vedic inheritance, which was the centre of practices of masters like Ramkrishna Paramhamsa, Sri Aurobindo and Satyananda Paramhamsa of Bihar School of Yoga, has come in the ambit of scepticism and ridicule. It has been grossly misrepresented, owing to which people today have reservations in associating themselves with Tantra and its practitioners.
At Dhyan Ashram, we are committed to the task of restoring to these sciences their lost glory, so that they may be put to the use of benefitting mankind.

• Tantra is NOT black magic or hoodoo or occult practices.
• Tantra is NOT about hurting or harming anyone.
• Tantra is NOT about blood, bones and sacrifices.
• Tantra is NOT pornography.

Black magic, hoodoo and occult practices are a very low form associated with the lower lokas – those of bhutaal, rasataal, pataal and the like. A tantric practitioner will never indulge in it. In fact the effect of black magic does not even touch the Tantric practitioner, for he is protected from lower forms of energy.

• Expansion and Liberation
  Tantra is the route prescribed for the man in kaliyug for expansion and liberation. The word TANTRA is a combination of two words – tanauti and trayati, i.e. expansion and liberation. Just as water expands on heating and then transforms into vapour state (free state) which is also its purest form, tantra calls for intense tapa and ultimately leads to purification of self by aiding the creation.
• Interaction with Divine Energies
  The science of tantra was given by none other than Dev-Adidev-Mahadev Shiva. Lord Shiva created 64 Yantras and 64 Mantras of various deities to attain various objectives and siddhis. For His consort AdiShakti, He created the Sri Yantra which is the equivalent of all the other 64 Yantras and Mantras put together. A true tantric practitioner accesses the subtler dimensions through these codified sounds (mantras) and geometric patterns (yantras) to aid the positive forces in Creation.
  To gauge the power of this science, let us take example of the Sri Yantra. The Devi resides at the central bindu of Sri Yantra. There are a total of 108 Devis in the 9 avaranas of Sri Yantra. Ganesha, Soorya, Vishnu and Shiva reside at the four corners of the Sri Yantra. All the eight Lakshmi, Saraswati, the Nityas, the Yoginis and in fact every Devi controlling each and every aspect of our life and the world reside in the Sri Yantra. Devi Mahalakshmi Matrika is worshipped for wealth, Devi Maheswari Matrika is worshipped for business & job and Devi Kaumari Matrika is worshipped for children. The Puja of Sri Yantra holds in itself an amazing force.
• Protection from Evil
  Tantra is also used to form protective shields to ward off negative forces. However, the purpose is solely defensive and never to cause harm. In fact Tantra has very strict code of conduct. It is said that he who harms another living being through the pious practice of tantra will get the negative effect 1,000 times the intensity.

• You become what you follow. A practitioner of Tantra exudes health, glow, vitality and attraction. He/she possesses a disease-free body and pleasing presence.
  On the contrary, a practitioner of black magic would have a scary appearance, bodily deformities or ailments and a repulsive presence.
• A true tantric is beyond the realm of maya. Tantra is a pious science that is channelised by the grace of Guru. Any attempt to tie with material profits, will cause it to lose its efficacy.
  Therefore, anyone who attaches a fee to the practice is definitely not a tantric.

THE FINAL WORD
Denounce the imposters, not the subject.
