Bodily happiness: The 1st is the house of the physical body. The 6th is the house of illness and obstacles. The 1st lord in the 6th house thus forms a symbol of the physical body surrounded by illness. This placement decreases the extent to which our bodies are strong and unburdened, and therefore can enjoy sensual and physical happiness.
This image is subject to the influence of surrounding astrological conditions. Of course, all symbolic images are, but this one is particularly so. The incarnation of the Vedic Supreme Personality of Godhead, Sri Krishna, was born with the 1st lord in the 6th house. He of course enjoyed the highest happiness and health. However it is a fact that the “body” of Godhead is a transcendental substance, not a physical object. Therefore it is noteworthy that this astrological position reveals the non-material, non-physical nature of the enjoyments Krishna displayed during his time on earth. Besides this spiritual point, it also illustrates astrological principles. The 1st lord of Sri Krishna was in the 6th house in an exceedingly elevated “raja yoga” – thus the 1st lord in the 6th house under positive conditions brings a result opposite to what the image suggestion. In other words, the image suggested by the author is the “stock” image related to the condition in isolation of other factors. If the other factors are good, the stock image takes a positive permutation, and visa versa. Krishna is an example of this. His 1st lord in the 6th house in one sense shows that he was completely untouched by physical pleasures; but because that 1st lord was in such a positive condition it contributed to his enjoying life on an unparalleled, transcendental level.
Enemies: The 1st is the house of the self, the 6th is the house of enemies. So the 1st lord in the 6th creates the symbol of the self feeling surrounded by enemies, troubles, worries, difficulties, detractors, and obstacles.
Again, the 1st lord in the 6th is very sensitive to surrounding conditions. Sri Krishna, for example, was constantly surrounded by enemies from the moment of his birth till the end of his life. But because the situations surrounding this 1st lord were so strong and positive, the outcome contributed to Krishna’s ability to very thoroughly and almost effortlessly crush each and every one of those relentlessly approaching enemies. The lesson here is that the 1st lord in the 6th house brings many challenges to us, but challenges are opportunities to become powerful and great. With some good influence on our 1st lord and with some good volition and determination on our part, the 1st lord in the 6th can make us conquer a host of enemies and rise about a field of obstacles.
