Dave: Dear swamiji pranam, how are you? Swamiji, I just wanted to know, that when the soul leaves the body then how long does it take for it to get a new body?(as per vedas) many thanks swamiji and thanks for taking time to answer my questions.
Swami Ram Swarup: My blessings to you, I am fine. In this connection I paste my articles below.

QUALITIES OF SOULS (JEEVATAMA)

Soul is alive. Soul has to face the result of his deeds. Soul takes body of human beings, animals, birds, trees etc., according to deeds of past lives. Soul feels sorrow, happiness etc., through body. When soul leaves body, it feels nothing but carries all karma to be faced in next birth through his chitta’s (chitta) vritti (vritti).

Souls are innumerable but are constant in number having similar qualities like being pure, immortal, alive etc. Soul is infinitesimally small, is invisible. The bodies of all living beings contain souls.

Not God but soul has desire, hatred/malice, merriment, sufferings, attachment etc. While attracting itself towards materialistic articles made of prakriti soul forgets his original form. As a result, soul recognizes himself as body. This is the stage of soul being unwise.

“NA TAM VIDATH YA IMA JAJAANANYUDYUSHMAKAMANTARAM BABHOOVA,
NEEHAREINN PRAVRITA JALAPYA CHASUTRIP UKTHASHASCHARANTI.”
(RIGVEDA MANTRA 10/82/7)

(TAM) that God (NA) not ( VIDATH) known (YAH) who (EMA) all worlds (JAJANN) creates and (YAT) from you (ANYAT) separate from other souls(YUSHMAKAM) from you (ANTARAM) with in all (BABHOOVA) is (NIHAREINN) fog like smoke (YAT) that God (PRAVARITAHA) covered (JALAPYAHA) baseless discussion (ASUTRIPAHA) satisfied only in Prann [breathing system] (UKTHASHASAHA) only paying lip service (CHARANTI) deals or behaves.

Meaning: Like an invisible matter which is covered with fog similarly dealing in only lip service and indulging in baseless discussion and are satisfied in their breathing system, Oh! Man-woman, you do not know the God who creates the five matters/universe and the God who is separate from other souls and who is within all.

After death

Yajurveda mantra 3/55, says, “DEVAIYAH JANAH NAH PUNAH MANAH DADATU” i.e., by blessings (preach and true education of Vedas) may learned Acharya give us next birth of human being so that we may again be able to learn the truth of Vedas and to get salvation. So one must always adopt true path by which he gets rebirth of human being to continue the real
spiritualism to get salvation etc., because Atharvaveda mantra 9/10/16 further says that human being who has done pious deeds and adopted true path they get pious human body in the next birth, otherwise soul gets the lowest/contemptible body, like animals, birds etc. Mantra is APAANG PRAANGETI SWDHAYAA GRIBHITAH AMARTYO MARTYENAA SAYONIHI. TA SHASHVANTA VISHUCHINA VIYANTA NYA NYAM CHIKYURN NI CHIKYURNYAM.

Soul according to its good or bad deeds(APANGETI) takes bodies of animals, birds, insects etc., and (PRANG) bodies of Rishis, Munis, i.e., (uuch Yoni) best bodies after leaving the present body. The soul (SWDHAYAA GRIBHITAH) duly attached with its own power of taking birth according to pious deeds and sins, enters other bodies (AMARTAYAH) though the soul is away from death, being immortal but after death of bodies, takes new bodies. These ideas of Vedas has very well been mentioned in Bhagwad Geeta shlok 2/20 wherein Yogeshwar Shri Krishna says (AJO NITYAH SHASHWATOAYAM PURAANNO NA HANYTE HANYAMANNE SHARIRE ) i.e., the soul is (AJAH NITAYAH SHASHWATOH) never takes birth and is eternal (NAHANYATE HANAYMANNE SHARIRE) in fact after death of body too soul is never dead being immortal. (TASHASHVANTA) this process of death and birth of bodies and souls is eternal.

(VISHUCHINA VYANTA) soul and bodies go far away to different directions [soul goes to Savita etc., {given below} according to Yajurveda chapter 39 and then takes birth and gets another body and five elements of body go to space and are mixed within air, fire etc., according to Yajurveda mantra 40/15] (ANYAM NICHIKYHU) many learned know about this fact (ANYAM NICHIKYHU) another who lack knowledge of Vedas, do not know the fact, i.e., we mostly know our body but not ourselves, i.e., soul. Death is sure i.e., the body will have to be cremated one day.

In Atharvaveda mantra 8/8/11 ‘Yamdut’ means = ‘YAM’ means God, and ‘dut’ means storm, cyclone, flood, earthquake, heavy rains, etc., etc., in mantra the air is Yam. So when a soul is to leave the body then by the power of God, sutratma air enters the body and takes the soul out of it then goes to Savita, etc.

In 39th chapter of Yajurveda the process of this cremation is mentioned. This process is also called as “NARMEDH YAJYEN”, “PURUSH MEDH YAJYEN” and “DAH KARAM” and “ANTEYESHATI KARAM”. Atharvaveda mantra 10/8/26 says “YEH CHAKAR SAH JAJAR” means He (God) who makes the body, He destroys the same one day. Sense of Yajurveda mantra 39/5 is that when the soul leaves the body then the soul wanders in so many places, takes another body according to its previous deeds (karmas). Yajurveda mantra 39/6 says that the soul after leaving the body, on the first day goes to Savita (sun), second day agnihi (fire), third Vaayu (normal air), fourth Aditya, fifth chandrma (moon), sixth ritu (seasons), seventh marutah, eighth brihaspati (tiniest air), ninth mitrah (breathing), tenth varunah (udan air), eleventh indrah (electricity), twelfth Vishvedevah (in all divine qualities). Then, after wandering in sky, gets body according to previous deeds. So these twelve days are completed, then after 13 days the soul takes another body. Rigveda mandal 10 sukta 135 says that normally soul after getting body faces the result of its past lives’ deeds and under influence of illusion (duly attracted towards illusion) does sins and again gets birth to face the sins. The soul is immortal and always separate from body. When an aspirant meets with a learned Acharya and gets spiritual education, then the fourth mantra says that the soul gets salvation.
