Let us do general interpretation of Nehru’s spirituality in chart. To see spirituality everything should be taken into account. Every house is involved in it. But we shall take the most important houses that are ascendant , 5th, 9th, 10th, 12th and 8th (9th from 12th) house. These are the most important houses,10th is taken because it is karma house. We should take only Varga chart D-9 because it is related to 9th house.
Now lets see Lagan (ascendant) first. Ascendant lord is in ascendant in the nakshatra of 12th house lord which is the house of liberation for the Cancer ascendant and in Navansha chart it is in 12th house in the navansha of Jupiter who is 9th lord in the lagan chart. Moon is his Atmakarak. Therefore Lagan lord and lagan is connected to 9th and 12th house. He was not born as a petty worldly man, he was born with a higher purpose.

Second thing -9th lord is aspected by strongest planet in Cancer and the most auspicious Mars, the lord of 5th house ( Purva Punya ) which gives profound leaning, devotion, religious mindedness, wisdom, discrimination between virtue and sin etc. Mars is lord of 10th house also where it is executed. Venus is depositor of Sun-Sat-Mars and Mercury sitting in his own house and is lord of 11th house i.e.. realization of any deed of this ascendant. Venus is in the constellation of Rahu in 12th house in Gemini who is in his own nakshatra. It is aspected by Jupiter the 9th lord from sixth house hence it is directly connected with 9th, 4th,3rd and 6th house. 6th house is 10th from 9th that means here Jupiter will prosper the 9th house significations. 9th lord Jupiter is also 6th lord which is mool trikon rashi and 6th lord in 6th forms Harshan yoga. Jupiter the 9th lord and Mars the 5th lord are in mutual kendra forming strong and auspicious Raja Yoga. Jupiter forms a auspicious Hari Yoga also (Venus-Jupiter-Mercury are 2nd and 12th place from 2nd lord Sun) in his chart. There are 4 planets in mool trikon and sign of exaltation (Venus, Jupiter and Ketu-Rahu), ancient astrology texts say that even a lowly born becomes a king. Jupiter is in nakshatra of Venus who is conjunct with 12Th lord Mercury in the same Nakshatra Swati which is associated with goddess of learning. Lord of Swati nakshatra is Rahu in 12th house in his own nakshatra Ardra ruled by Rudra, who is lord of Vidya ईशानः सर्वविद्यानामीश्वरः सर्वभूतानां ब्रह्माधि- पतिर्ब्रह्मणोऽधिपतिर्ब्रह्मा शिवो मे अस्तु सदाशिवोम् ॥ according to Hindu scriptures and also Bhagawat Puran.

In Kalchakra his Venus-Mercury and Mars are situated in Ishan direction hence all the major planets have blessing of God. His energy chakra begins from Moon nakshatra Ashlesha from north ruled by Kuber and ends at Rahu in North-west aspected by Jupiter the 9th lord and Vayu is the element of Swati in which lord of 12th is situated. In Navansha chart the depositor of Mars-Sun-Sat-Mer is in conjunction with Moon in 12th and aspected by Jupiter from 8th which is 9th from 12th. In Navansha Venus is Yogakaraka and Jupiter is 12th lord and 3rd lord. It is fully manifested in his writing, in his international politics and his secularism. Rudra Shiva is the most secular God in Hindu pantheon. Osho Rajneesh calls him Modern Bodhisattva in his autobiography.

Interestingly the Navansha is of his 7th house hence Saturn the lord of 8th house have big stake in his spiritual development and also problems in his life. 8th house is said to be the store house of past karma. Prashara says that if from Moon or Lagan Navansha of marak houses is rising then in the period paap-marak planet one gets adverse effect. His Moon and Venus in 12th house in the navansha of 6th lord of lagan chart aspected by 6th lord from 8th in navansha, hence during this period in Venus mahadsha, he was struggling and faced imprisonment. But he was a household, not an ascetic. Saturn aspects 12th lord and Venus both in Lagan chart and the nakshatra lord of both is Rahu who is sitting here in the sign of Saturn and is aspected by Saturn from 7th house. Saturn is in 2nd house in Magha nakshatra of Ketu in lagan chart, which is nakshatra of dynasty. He became founder of Nehru Dynasty. In Navansha Sun is conjunct with Ketu and Saturn in 7th house and 5th lord of purva punya is aspecting them sitting in his own sign Aries(Ruchak Yoga). KETU the lord of Magha is with Jupiter in his own nakshatra. Hence his purva punya was very strong, he was a family man, the builder of a strong nation INDIA and a great spiritualist, statesman and leader. He was a perfect Karma Yogi as for as Gita’s Karma Yoga is concerned. Gita says that he who does everything for the welfare of the people (loka) is the greatest Yogi. He did not serve a baniya, he served people of India and founded everything for them. In Puranas such auspicious birth were called incarnation of Gods.
