The Hindu Lingham is identical with "Jacob's Pillar" – most undeniably. But the difference, as said, seems to consist in that the esoteric significance of the Lingham was too truly sacred and metaphysical to be revealed to the profane and the vulgar; hence its superficial appearance was left to the speculations of the mob. […]
Both India and Egypt had and have their sacred lotuses, symbolic of the same "Holy of Holies" – the Lotus growing in the water, a double feminine symbol – the bearer of its own seed and root of all. Viraj and Horus are both male symbols, emanating from androgyne Nature, one from Brahma and his female counterpart Vach, the other, from Osiris and Isis – never from the One infinite God. In the Judaeo-Christian systems it is different. Whereas the lotus, containing Brahma, the Universe, is shown growing out of Vishnu's navel, the Central point in the Waters of Infinite Space, and whereas Horus springs from the lotus of the Celestial Nile – all these abstract pantheistic ideas are dwarfed and made terrestrially concrete in the Bible: one is almost inclined to say that in the esoteric they are grosser and still more anthropomorphic, than in their exoteric rendering. Take as an example the same symbol, even in its Christian application; the lilies in the hand of the Archangel Gabriel (Luke i. 28). […]
[H]ow could those who invented the stupendous scheme now known as the Bible […] feel reverence for such a phallic symbol […] as Jehovah is shown most undeniably to be in the Kabalistic works? How could anyone worthy of the name of a philosopher, and knowing the real secret meaning of their "pillar of Jacob," their Bethel, oil-anointed phalli, and their "Brazen Serpent," worship such a gross symbol, and minister unto it, seeing in it their "Covenant" – the Lord Himself! Let the reader turn to Gemara Sanhedrin and judge. As various writers have shown, and as brutally stated in Hargrave Jennings' Phallicism (p. 67) "We know from the Jewish records that the Ark contained a table of stone … that stone was phallic, and yet identical with the sacred name Jehovah … which written in unpointed Hebrew with four letters, is J-E-V-E or JHVH (the H being merely an aspirate and the same as E). This process leaves us the two letters I and V (in another form U); then if we place the I in the U we have the 'Holy of Holies'; we also have the Lingha and Yoni and Argha of the Hindus, the Isvara and 'supreme Lord'; and here we have the whole secret of its mystic and arc-celestial import, confirmed in itself by being identical with the Linyoni of the Ark of the Covenant."
